On page 132 of I, Reality and Subjectivity, the following question and answer can be found. 

Q. What is meant by the term "mystic"? 

A. The mystic knows, experiences, and identifies with the Self as both context and content, that is, context is content. The content of the ego is transitory and a product of perception and, like a movie, it has no independent existence. The content of perception is an automatic byproduct of positionality and goes hand in hand with the creation of the illusions of perception. Science is the authority of the linear domain and the Newtonian paradigm; the mystic is the authority of the nonlinear domain.
