In descriptions of psychedelic experiences, the term is used synonymously with ego-loss to refer to (temporary) loss of one's sense of self due to the use of psychedelics. The term was used as such by Timothy Leary et al. to describe the death of the ego in the first phase of an LSD trip, in which a "complete transcendence" of the self occurs. The concept is also used in contemporary New Age spirituality and in the modern understanding of Eastern religions to describe a permanent loss of "attachment to a separate sense of self" and self-centeredness. This conception is an influential part of Eckhart Tolle's teachings, where Ego is presented as an accumulation of thoughts and emotions, continuously identified with, which creates the idea and feeling of being a separate entity from one's self, and only by disidentifying one's consciousness from it can one truly be free from suffering.
