Ego death is an experience[dubious ] that is said to reveal the illusory aspect of the ego, sometimes undergone by mystics, shamans, monks, psychonauts and others interested in exploring the depths of the mind.
The practice of ego death as a deliberately sought "mystical experience" in some ways is said to overlap with, but is nevertheless distinct from, traditional teachings concerning enlightenment/"Nirvana" (in Buddhism) or "Moksha" (in Hinduism and Jainism), which might perhaps be better understood as transcendence of the notion that one even has any actual, non-illusory "ego" with which to experience "death" in the first place.
An ego death is said to be characterized as the perceived loss of boundaries between self and environment, a sense of the loss of "control", the loss of the accustomed feeling of existing as a "personal agent", and lose "cognitive-association binding". This "perceived loss of boundaries between self and environment" is said to be experienced through a sensation that one is the whole universe (and therefore there is no need to differentiate the "I" from the "universe") or by simply acknowledging the "I" does not exist.
According to Stanislav Grof,
Methods of inducing the experience 
Modern claims of ego death 
Some famous examples of people claiming to have had the experience are Ramana Maharshi and U. G. Krishnamurti. More recently Eckhart Tolle has claimed that he underwent the experience after having suffered from long periods of suicidal depression. He says he woke up in the middle of that night and thought,
|“||I couldn’t live with myself any longer. And in this a question arose without an answer: who is the ‘I’ that cannot live with the self? What is the self? I felt drawn into a void. I didn’t know at the time that what really happened was the mind-made self, with its heaviness, its problems, that lives between the unsatisfying past and the fearful future, collapsed. It dissolved.||”|
Tolle recalls going out for a walk in London the next morning, and finding that “everything was miraculous, deeply peaceful. Even the traffic."
Many users of psychedelics like psilocybin, DMT, LSD, DXM or Ketamine report experiences of ego death along with other mystical experiences common with psychedelic substances. This becomes apparent on study of psychedelic reports where themes relating to dying and mortality, transcendence, and expansion of consciousness are commonly observed.
