My Self, as I perceive it, is difficult to describe. Words are too poor. I could describe it as feeling life or Life Force within me--pure beingness. But it is also almost experienced as a separate "other," as Krishnmurti described it, yet I know it is me.
It has incredible energy, dancing, turning, moving, and when I look within, in my subjective inner space, it is an amorphous white light expending from below my belly to my neck and fills my gut and chest.
But it's boundaries are always changing, sensitive to me and to the world, sending filaments of awareness into the world around,feeling it from my heart.
I identify with it. It is I. It is me. It is me more than my body is me. Emotions pass through it leaving ripples in the light and energy field. Feeling myself is pure delight. The constant circulation of energies and light is fascinating to behold and even more fascinating to feel. I need no companion because I know myself.
Besides that core of Self, around me is my sense of presence that fills the space around my body and extending into the room like an electromagnetic field sensing the room's own sentience.
But for the life of me, I cannot see how the world can be a projection of the Self. Yes, the Self is visual, the Self has a tactile sense and emotional feelings. But even after 45 years of no-self and unity experiences my basic state is still that of a separately embodied Self, and I wish that all separately embodied Selves could get to know their own Self, for when they do, everything changes. It is the same Self of everyone. It is divinity itself.
So, I as witness can observe the world, the human Ed with his body, mind, and emotions, and the Self. Conceptually they can be separated, but experientially they are one experience.
When the mind, I as mind, turns its attention towards the external world and then the internal, there are similarities, but I cannot perceive any direct mapping or mechanism of one into the other.
But then, who actually believed that such connections can actually be felt or intuited. It is just as likely as that which lies prior to Consciousness, which includes both the internal and external worlds, is the author of both worlds, that is why we have the similarity that we do have between the two, and thus the basic structures will never be directly observable, they can only be indirectly inferred based on experience, hypothesis, experiment, and proof.
