the recapitulation, which consisted of a systematic scrutiny of one’s life, segment by segment, an examination made not in the light of criticism or … - Carlos Castañeda

This is the sorcerers’ explanation. The nagual is the unspeakable. All the possible feelings and beings and selves float in it like barges, peaceful, unaltered, forever. Then the glue of life binds some of them together. You yourself found that out last night, and so did Pablito, and so did Genaro the time he journeyed into the unknown, and so did I. When the glue of life binds those feelings together a being is created, a being that loses the sense of its true nature and becomes blinded by the glare and clamor of the area where beings hover, the tonal. The tonal is where all the unified organization exists. A being pops into the tonal once the force of life has bound all the needed feelings together. I said to you once that the tonal begins at birth and ends at death; I said that because I know that as soon as the force of life leaves the body all those single awarenesses disintegrate and go back again to where they came from, the nagual.

The aim of sorcerers is to reach a state of total awareness in order to experience all the possibilities of perception available to man. This state of awareness even implies an alternative way of dying.

"Are you angry at me, don Juan?" I asked when he returned. He seemed surprised at my question.
"No! I'm never angry at anybody! No human being can do anything important enough for that. You get
angry at people when you feel that their acts are important. I don't feel that way any longer."
