“Her Dream Became a Nightmare as She Probed the Alien Ruins.”
From the back cover:
The human personality has been defined by leading psychologists as the integrated and dynamic organization of physical, mental, moral and social qualities. A personality is the product of heredity and environment. Every experience records itself in the neurons of the brain producing an almost infinite number of possible combinations. Brains are as individual as fingerprints.
In an infinite universe, however, there is a possibility that somewhere – separated by vast distances of Time and Space – two exactly similar brains exist. The strange telepathic bond between identical twins could operate between identical minds.
Melinda Tracey was a practical, intelligent, modern girl who didn’t believe in dreams – even recurring dreams – but her odd sleep experiences of the ruined city, and the strangely-suited figure who searched it, disturbed her considerably.
What incredible psychological bond linked Melinda to the lonely stranger, probing the wreckage of an alien metropolis?

Badger Books were published between 1959 and 1967 in a number of genres, predominantly war, westerns, romance, supernatural and science fiction. In common with other “pulp” or mass-market publishers of the time, Badger Books focused on quantity rather than quality. A new title in each of the major genres appeared each month, generally written to tight deadlines by low-paid authors. One of the most remarkable facts about Badger Books is that much of its output was produced by just two authors (using a range of house names and other pseudonyms). John Glasby (over 300 novels and short stories) and Robert Lionel Fanthorpe (over 200 novels and stories). [Wikipedia]
Scientists have been developing astounding new tools for exploring neural circuits that underlie brain function throughout the first five years of the National Institutes of Health’s Brain Research through Advancing Innovative Neurotechnologies® (BRAIN) Initiative. Now, the NIH has announced its continued support for these projects by funding over 180 new BRAIN Initiative awards, bringing the total 2019 budget for the program to more than $424 million.

for those who speak this language: these are the apical tufts of 2 cortical layer V pyramidal cells filled with biocytin and stained with a Texas red / avidin-D conjugate, then counterstained with a green fluorescent nissl stain.
"In a new study, Yale researchers show that a single dose of psilocybin given to mice prompted an immediate and long-lasting increase in connections between neurons. “We not only saw a 10% increase in the number of neuronal connections, but also they were on average about 10% larger, so the connections were stronger as well,” said Yale’s Alex Kwan, associate professor of psychiatry and of neuroscience and senior author of the paper.
Previous laboratory experiments had shown promise that psilocybin, as well as the anesthetic ketamine, can decrease depression. The new Yale research found that these compounds increase the density of dendritic spines, small protrusions found on nerve cells which aid in the transmission of information between neurons. Chronic stress and depression are known to reduce the number of these neuronal connections.
“It was a real surprise to see such enduring changes from just one dose of psilocybin,” he said. “These new connections may be the structural changes the brain uses to store new experiences.” — SciTech
From paper in Neuron (full-text PDF): "We found that a single dose of psilocybin led to ∼10% increases in spine size and density, driven by an elevated spine formation rate. The structural remodeling occurred quickly within 24 h and was persistent 1 month later. Psilocybin also ameliorated stress-related behavioral deficit and elevated excitatory neurotransmission. Overall, the results demonstrate that psilocybin-evoked synaptic rewiring in the cortex is fast and enduring, potentially providing a structural trace for long-term integration of experiences and lasting beneficial actions."

My hands are still sore after a sprawl while walking the dogs last night. It was a bit of a struggle to hold the camera steady. And yes Ralph, these pictures were once again taken during my so called long lunch breaks.

The dogs belonging to the piano's fairies can be found in a wide variety of colours. They are sometimes described as white with red ears may be found in all colours of the keybord.
In Kabbalah, Renaissance magic, and alchemy, the language of the birds was considered a secret and perfect language and the key to perfect knowledge, sometimes also called the langue verte, or green language (Jean Julien Fulcanelli, Heinrich Cornelius Agrippa de occulta philosophia,A black dog is a spectral or demonic entity found primarily in the folklore of the British Isles."Their discovery that certain neurons have “music selectivity” stirs questions about the role of music in human life. Why do our brains contain music-selective neurons? Could some evolutionary purpose have led to neurons devoted to music? McDermott says the study can’t answer such questions. But he is excited by the fact that it shows music has a unique biological effect. 'We presume those neurons are doing something in relation to the analysis of music that allows you to extract structure, following melodies or rhythms, or maybe extract emotion,' he says." The black dog is essentially a nocturnal apparition, some of them shapeshifters, and are often said to be associated with the Devil or described as a ghost or hellhound. Its appearance was regarded as a portent of death. It is generally supposed to be larger than a normal dog and often has large glowing eyes.[ It is sometimes associated with electrical storms (such as Black Shuck's appearance at Bungay, Suffolk) and also with crossroads, places of execution and ancient pathways. The origins of the black dog are difficult to discern. It is uncertain whether the creature originated in the Celtic or Germanic elements of British culture. Throughout European mythology, dogs have been associated with death. Examples of this are the Cŵn Annwn (Welsh),Garmr (Norse) and Cerberus (Greek), all of whom were in some way guardians of the Underworld. This association seems to be due to the scavenging habits of dogs. It is possible that the black dog is a survival of these beliefs. Black dogs are generally regarded as sinister or malevolent, and a few (such as the Barghest and Shuck) are said to be directly harmful. They may also serve as familiar spirits for witches and warlocks. Some black dogs, however, such as the Gurt Dog in Somerset and the Black Dog of the Hanging Hills in Connecticut,are said to behave benevolently. Some, known as guardian black dogs, guide travellers at night onto the right path or guard them from danger.his thought leads to another, which takes us into unexplored and perhaps unexplorable regions of Greek religious history. The chief claim made in Pithetaerus's preposterous speech to the Birds is, after all, partly true. The Birds were objects of worship to the Minoans and the early inhabitants of Greece before Zeus and his Olympian commando descended upon the peninsula. Birds were not gods; Pithetaerus does not quite say they were. Yet the bird perched on the sacred Double Axe or the pillar-tree was the Numen of the axe or the tree. Technically, the Language of the Birds - as it was often described in folk tales and myths in general - literally referred to what anyone might assume it did: the way birds communicate. And, to be able to understand this language endowed one with special powers, knowledge and abilities. As time went on, however, the phrase took on more occult implications. in medieval France it became the secret "Green Language" of the Freemasons and Knights Templar - la langue des oiseaux - and was possibly also utilized by the Troubadours (or Trouvères). During the Renaissance, there were apparently a number of musical languages inspired by birdsong, although at least a few of these were probably composed of simple signals in ways similar to those used by the indigenous peoples of the Americas and elsewhere.When I first began using the phrase "the Language of the Birds" to describe my own understanding of mysticism, I had almost no formal knowledge of the phrase's history; I had initially found it in reference to a Sufi text, and was attracted to it in a poetic sense. After all, the phrase has a nice resonance to it. Eventually, however, I began to equate it with language of the higher consciousness, specifically that of the creative muse and its role in automatism. At the same time, you began to intuit there was a transdimensional aspect to it, which you referred to as "the memory of sound". That is, while there is the physicality of sound and its effect on our senses, there are also immaterial, subliminal codes embedded in sound which effect us both emotionally and spiritually in ways that are not currently understood. In this sense, music is, in fact, magic.The Minoans believed, as Nilson says, that the gods - or, to put it more exactly, the divine power - appeared in the form of birds. Again, the most important and wide-spread method of communication with the divine power was by augury. The birds knew the weather; they knew when good luck or bad was to be expected; they gave clear warning of the future to those who could read their messages. Could they have known what was coming so well unless indeed it was partly they who made it come? "Sometimes mythological birds create more than the physical world. Cultures in northern Europe and Asia credited birds with establishing their social orders, especially kingships. A golden-winged eagle was said to have put the first Mongol emperor on his throne. The Japanese believed that sacred birds guided their second emperor in conquering his enemies before the founding of his dynasty. The Magyar people claimed that a giant eagle, falcon, or hawk had led their first king into Hungary, where he founded their nation. The Magyars looked upon this bird as their mythical ancestor...Many myths have linked birds to the arrival of life or death. With their power of flight, these winged creatures were seen as carriers or symbols of the human soul, or as the soul itself, flying heavenward after a person died. A bird may represent both the soul of the dead and a deity at the same time. Some cultures have associated birds with birth, claiming that a person’s soul arrived on earth in bird form."Lastly, we come to the Music Box, the third element of this introduction. Portions of it first made its appearance on this blog in February around Valentine's Day, and was meant to be the metaphorical fulcrum about which my "Ode to Love" was spun. That particular post died in the water, however - for numerous reasons - and, although the initial post is still online - and might be referred to in the future - you may as well consider this one its replacement.
In "Still Life with Music Box" the floating panels of the box I created last month have finally come together into an actual (although virtual) object. In order to visualize the box, I inadvertently made a model of it with cardboard and inkjet prints and then snapped its photograph. A great deal more work was involved, but amongst the objects, only three were entirely contrived... and I'm guessing it's pretty obvious which ones. I'm no master, but I did the best I could (without driving myself insane). (Hint: The wooden table supporting the objects is real enough - it was created by my grandfather at some point around the turn of the last century.)
As it so happens, as lyrical as the music box appears, it's creation was the result of a geometrical inquiry... an inquiry that's particularly relevant in any discussion of love and alchemy when you come right down to it, but I'll save the geometry for the next post and reflect on the music box's general importance here; that is, in its role as a generator of music, and, at the same time, a collector of love tokens, that is, a keepsake box.
Initially, I referred to the music box as the "Love Box"... totally overlooking the fact that the actual term is American slang for a certain portion of a woman's anatomy. That being said, that "love box" has the particularly feminine connotations it does, is not really inappropriate here. Woman, after all, do have a peculiar predilection for keeping memorable items in special boxes, especially as young girls. Our little magic boxes... full of talismanic detritus we've collected over the years... a coin, jewelry, a shred of hair, a crumbling flower head, a photo, a signature, stones, bones... whatever. Generally the tokens are kept to remind us of lovers or loved ones... small trophies for experiences that may eventually retreat into a mental shadowland in the same way the objects themselves have retreated into the shadowy recesses of the box. But, no matter. The box becomes a sort of artificial memory bank... a collection of three-dimensional objects representing transdimensional events in the same way a collection of symbols do.
In the end, whether we're talking about musical codes, alchemical codes, or the enigmatic chemistry of love and attraction, some type of hidden language is involved... as is some kind of communication that lies outside the bounds of what is consciously understood. When we find ourselves in tears while listening to an old, wistful tune, or find ourselves suddenly uplifted by the memory of a lover's smile, although utterly immaterial, the experience is real, and has as much power to move us, inspire us, and inform us as any collection of words (up to and including the ones you are presently reading)! And that, is the Language of the Birds.
As it stands, for all our technological prowess, we, as a species, have not inwardly changed very much from the days our savage ancestors danced naked around a fire; the difference being, our savage ancestors very likely understood a few things we modern specimens of humanity have forgotten. And, one of those "things" is the origin of music. My guess is that if prehistoric humans could somehow convey to us certain facets of our prehistory, they might inform us that humans did not, after all, invent music. The were taught.
Well, do the math. Songbirds are thought to have evolved 50 million years ago in an area which is now Australia. Modern humans, on the other hand, are generally considered to have arisen out of Africa a paltry 250,000 years old. In other words, birds were singing millions of years before humans even discovered the coveted fire they'd eventually dance around."Their discovery that certain neurons have “music selectivity” stirs questions about the role of music in human life. Why do our brains contain music-selective neurons? Could some evolutionary purpose have led to neurons devoted to music? McDermott says the study can’t answer such questions. But he is excited by the fact that it shows music has a unique biological effect. 'We presume those neurons are doing something in relation to the analysis of music that allows you to extract structure, following melodies or rhythms, or maybe extract emotion,' he says."
"As Spring reaches its midpoint, night and day stand in perfect balance, with light on the increase. The young Sun God now celebrates a hierogamy (sacred marriage) with the young Maiden Goddess, who conceives. In nine months, she will again become the Great Mother. It is a time of great fertility, new growth, and newborn animals."
- From a short entry for the Wiccan holiday, Ostara (March 20th), found on this page.
"Hieros gamos or Hierogamy (Greek ἱερὸς γάμος, ἱερογαμία "holy marriage") refers to a sexual ritual that plays out a marriage between a god and a goddess, especially when enacted in a symbolic ritual where human participants represent the deities.
The notion of hieros gamos does not presuppose actual performance in ritual, but is also used in purely symbolic or mythological context, notably in alchemy and hence in Jungian psychology.
In Wicca, the Great Rite is a ritual based on the Hieros Gamos. It is generally enacted symbolically by a dagger being placed point first into a chalice, the action symbolizing the union of the male and female divine in the Hieros gamos. In British Traditional Wicca, the Great Rite is sometimes carried out in actuality by the High Priest and High Priestess."
- From the Wiki entry for Hieros gamos.
"One of the most fascinating explorations of the psychological analogues of alchemy was given to us by Jung in a lengthy essay not usually classified as one of his alchemical writings, entitled The Psychology of the Transference. In this study Jung employed the ten pictures illustrating the opus of alchemical transormation contained in a classic called Rosarium Philosophorum (Rosary of the Philosophers), where the dual powers of the "King" and "Queen" are shown to undergo a number of phases of their own mystico-erotic relationship and eventually unite in a new, androgynous being, called in the text "the noble Empress". The term "transference is used by Jung as a psychological synonym for love, which in interpersonal relations as well as in depth-psychological analysis serves the role of the great healer of the sorrows and injuries of living."
- From "Alchemical Eros" via C. G. Jung and the Alchemical Renewal by Stephen A. Hoeller, (an article from the Gnosis magazine archive).
"In this hermetic side of alchemy, the "philosopher's stone", supposed to to be the most tangible and dense crystalization or condensation of a subtle substance, became a metaphor for an inner potential of the spirit and reason to evolve from a lower state of imperfection and vice (symbolized by the base metals) to a higher state of enlightenment and perfection (symbolized by gold). In this view, spiritual elevation, the transmutation of metals, and the purification and rejuvenation of the body were seen to be manifestations of the same concept."
- From the Crystalinks entry for Philospher's Stone.
***
But, what do we really mean by phrases like "the realm of the psyche" or "spiritual elevation"? Obviously, this question (in various forms) has been at the heart of the world's philosophy the millisecond humanity became disconnected from its initial source. At some point, we simply forgot. No longer having any real understanding of our essential natures we - specifically those of us in the west - allowed the various spin-doctors to take over. "And all the king's horses and all the king's men, couldn't put Humpty (the egg) together again... "
Except for one thing. In spite of the failure on the part of "the king and his men", there is one force that could - and one force that always will - "put" us together again, and that is the force of Love. While the physical aspect of Love exists and is very important to us in a biological and psychological sense, Love also reminds us that we are, in essence, immaterial entities. We know that we are truly alive because we love. We are assured our lives have meaning because we love. We conceive of things like "eternity" and "forever" because we love.... and we know Love, like Life itself, cannot simply dissipate because, although it influences the material realm, it is not really of it. Love knows no atrophy.
Alchemy itself, as a psuedo-science and precursor to chemistry, was primarily founded upon the concept that there was some substance - the Philopher's Stone - that when procured a certain way via certain rituals could transform base materials literally into gold. This, in any case, is the general fable. But when one takes a peek at all the literature, and all the various graphic material pertaining to alchemy and the alchemists, one thing immediately becomes clear: alchemy was no mere chemistry experiment.
But, just what was alchemy exactly? What was really meant by "the Great Work"? In reality, there is no exact definition of alchemy. It seems to have slowly evolved both in the East and in the West, and, at all times, to have been both an exoteric as well as an esoteric inquiry. On one hand, the quest was to cure disease, attain immortality and transmute base substances... on the other the goal was divine and spiritual knowledge and the perfection of the soul. The Great Work was generally in reference to creating or attaining the Philosopher's Stone, but once again, the "stone" had both material and mystical properties. One might say the stone itself was merely metaphorical for a sublime state of being or for the secret of creation itself.
One might go further and intuit the true Philosopher's Stone was the force of Love, but this side of alchemy has been mostly ignored except in Hermetic philosophy, in which the heiros gamos (see quotes above), or the "mysterium conjunctionis" is a crucial part of the philosophy. It was not lost on Carl Jung, however, who wrote in Volume 14 (translatable text) of his Collected Works:
“In light of eternity, it is a wedding, a mysterium conjunctionis. The soul attains, as it were its missing half, it achieves wholeness.”
