Physical body is not the experience of physical body itself. Then, what experiences the physical body and perceives the world as a person. Therefore, one has to know with what the physical body is able to function itself and able to perceive the world as a person. Without the formless experiencer of the physical body, they call the physical body as dead body. Beginners have to start with this doubt and try to focus their attention on the formless experincer of the physical body. Next step is realizing "What is mind "and "What is substance of the mind".
Inner Revelation:
Within the waking experience the Atman[consciousness] identifies with the physical body and perceives the world as a person. Thus it becomes unaware of itself, by identifying itself, as a person. As a person perceiving the world within the waking experience, it is ignorant of its formless non-dual true nature. Once it becomes aware of the fact that neither the physical body nor the `I' is the true self, then the ignorance vanishes.
Furthermore, it becomes aware of the fact that waking experience is mere mirage. Thus to realize the fact that the burden and bondage felt in the duality is mere mirage created out of Tammany. The author of the Waking experience is Atman not the person who exists only within the Waking experience. Thus it is for the seeker to realize the fact that the real author of the experience of duality [mind or `I'] is Atman. Therefore the duality is not reality on the standpoint of Atman. Thus viewing judging the worldview on the base of false self [ego] will not help the seeker to unfold the mystery of the mind or duality. The duality exists as reality only on the false self. The truth cannot be realized on the base of false self. It is erroneous to claim the authorship of any experience as person, because person and the world are an experience within the illusory waking experience.
Many claim that they have acquired the self -knowledge, but only superficially. They really do not know what the self- knowledge is because they think `I' is self and body is not the self; no one has really grasped the knowledge of the true self. Very few will get this knowledge correctly and absorb it deeply. Once seeker understands the fact that `I' not the self but Atman is the true self, and everything else other then Atman is mere illusion with firm convection will realize the fact the nothing exists other then Atman or spirit.
When one reads the messages, first he may feel that it is boring, but when he attempts to read them again it starts sinking in. Then he will start reading and reflecting on them constantly. Once he gets a hang of it, he will never rest until he assimilates it.
Seeker Having stabilized in the Atman as self and capable of judging the worldview on the base of Atman as self , he will have a yard stick to judge what is truth and what is untruth. He can make the clear distinction between duality [untruth] and non-duality [truth].
The seeker who to sticks to the F.S guidance and reads the messages and reflect on it constantly for long time without asking any questions, his proximity to F.S guidance the capacity to grasp to receive this guidance becomes mature. His capacity to understand and assimilate it increases. Wisdom arises within him; it does not come from outside of him.
FORMLESS WITNESS WITNESSES THE EXPERIENCE OF DUALITY
Seeker must come to a firm decision. He must have the conviction neither the physical body not the `I' is the true self. Furthermore, seeker must have the firm conviction that Atman is the true self", which has no form, no name. When he stabilizes in that conviction it will give all the knowledge and all the secrets to him, and when the secrets are given to him, he transcend from the experience of duality mentally, and he will know that the whole experience of diversity is Atman because the whole experience is mere mirage created out of Atman.
Having gained all this knowledge, having understood what is what, a kind of quietude tranquility prevails. Illusion is transcended mentally and one becomes aware of the fact that the illusion is Atman through wisdom, in the midst of the illusion or experience of duality.
The duality does not disappear, but the ignorance, which was the cause of holding the duality as reality will disappear. Thus, one gets the wisdom of witnessing the waking experience on the base of the Atman, the true self, and becomes free from experiencing the birth, life and death as reality. And prevails eternally as birth- less and deathless self.
