It’s quite possible that DMT is released when humans meditate. DMT is one of the most powerful psychedelics known to humans and is found naturally in the human body. The idea is that through chanting and deep meditation large amounts of this hallucinogen are released causing mystical experiences along with hallucinations. I think I’m going to stay away from Eastern meditative practices. CRI has documented some harmful effects of Transcendental Meditation. Maybe these two things are related.

For more about DMT google DMT The Spirit Molecule. There’s also a book out by the same title.
