From DMT: The Spirit Molecule by Rick Strassman, M.D.
The three pillars of self, time, and space all undergo profound transfiguration in a mystical experience.
There no longer is any separation between the self and what is not the self. Personal identity and all of existence become one and the same. In fact, there is no "personal" identity because we understand at the most basic level the underlying unity and interdependence of all existence.
Past, present and future merge together into a timeless moment, the now of eternity. Time stops, inasmuch as it no longer "passes". There is existence, but it is not dependent upon time
