From Chapter 22 of Shri Sai Satcharita:

~~~~~

As the dark fortnight of every month wears out gradually, the moonlight also wanes in the same degree and on the newmoon day, we do not see the moon at all, nor do we get her light. Therefore, when the bright fortnight begins, people are very anxious to see the moon. On the first day, the moon is not seen and on the second day also she is not clearly visible. Then the people are asked to see the moon through an opening between the two branches of a tree, and when they begin to see through this aperture eagerly and after concentratedly, the distant small crescent of the moon comes, to their great delight, within their ken. Following this clue, let us try to see Baba's Light. Look at Baba's posture, how fine it is! He is sitting with His legs folded,the right leg held across the left knee. The fingers of His left hand are spread on the right-foot. On the right toe are spread His two fingers-the index and middle ones. By this posture Baba means to say, as it were-if you want to see My Light, be egoless and most humble and meditate on My toe through the opening between the two branches-index and middle fingers-and then you will be able to see My Light. This is the easiest means of attaining devotion.

Explanation By Robert First - Wolfpack DojoEvery learning process starts as a clean slate, an empty cup. A NOBODY begins by being a LEARNER. Any learning process takes time and hard work, thus one becomes a WORKER. When you work at something and really want it you will fight for it, evolving into a FIGHTER and when you fight for something you will be an ACHIEVER by definition, and to achieve is to be a WINNER. When you're a winner you teach others to win also and you evolve into a TEACHER. A good teacher will naturally be a LEADER and blaze the path for others. A leader must plan and understand therefore becoming a THINKER and in essence a thinker begins to understand with more depth and understanding without ego,thus evolving into a PHILOSOPHER which is like evolving the ego from a liquid state to a gas,which can take on all shapes and situations. This egoless state is enlightenment, "the greatest person is NOBODY".

Realizing that the confusion and the chaos in your mind have no origin, no cessation, and nowhere to dwell is the best protection. Shunyata is the best protection because it cuts the solidity of your beliefs. "I have my solid thought" or "This is my grand thought" or "My thought is so cute" or "In my thoughts I visualize a grand whatever" or "The star men came down and talked to me" or "Genghis Khan is present in my mind" or "Jesus Christ himself manifested in my mind" or "I have thought of a tremendous musical comedy, or how to conquer the world"---it could be anything, from that level down to : "How am I going to earn my living after this?" or "What is the best way for me to sharpen my personality so that I will be visible in the world?" or "How I hate my problems!" All of those schemes and thoughts and ideas are empty! If you look behind a mask, you see that it is hollow. There may be a few holes for the nostrils and mouth--but if you look behind it, it doesn't look like a face anymore, it is just junk with holes in it. Realizing that is your best protection. You realize that you are no longer the greatest artist at all, that you are not any of your big ideas. You realize that you are just authoring absurd, nonexistent things. That is the best protection for cutting confusion.

-- This slogan is related with the idea of carrying everything onto the path at the absolute bodhicitta level. It is very tricky. There is some possibility that when you hear that if you just simply meditate on the four kayas, everything is going to be protected, you may think that your kid is going to be protected, your brothers and sisters, your property and your motorcars. But this protection is not quite at that level ; it is shunyata protection, which is that you no longer have anywhere to dwell, you are suspended in shunyata. It is a very clever way of approaching the whole thing. You are not talking about egolessness here, you are trying to work out your protection. But you might find yourself being egoless and realizing that there is nothing to protect. So your protection is groundlessness. It is a very clinical approach in some sense. There can be no germs around if you have no ground on which to collect germs.

-- The idea of the four kayas is not particularly tantric, it is mahayanist high thinking. The kayas appear in the third turning of the wheel of the dharma in the Uttaratantra of Maitreya and in the Diamond Sutra. But at the same time, it is highly influenced by tantra. The whole thing is based on mahayana principles, but there is undercurrent of techniques that are borrowed from tantra. So the understanding is presented from the mahayana viewpoint, but the techniques are tantric.
