9.19 Man’s reality structure
Man’s body is as concrete as fingerprints.
Socialization shapes the human mind. Man tends to think that his mind is as concrete as his body, but his mind is far more formed by general societal influences and family unconscious.
Man can be aware of his body and mind but also of the source of his awareness, which means that without this Source he cannot be aware at all.
The awareness is autonomous, i.e. neither general nor concrete. It is an interface or interfacing between Life’s Source and Its creations. Without this interface man would not know that he exists.
I-sense is the awareness identified with the mind and body.
The awareness unidentified with the body-mind complex is the link between I-sense and the Life’s Source.
Non-identified awareness is when awareness is not (yet) identified with mind, body and any I-sense, and the natural process of existence, as seen in the body after birth, is simply Life playing itself out.
