Set, Setting, and Psychedelic Safety
The maxim that the psychedelic experience is shaped by "set and setting" — the mindset of the individual and the environment in which the substance is consumed — is perhaps the single most important practical principle in psychedelic science and practice. First articulated by Timothy Leary,...
Psychedelic Sexuality and Boundary Dissolution: When the Self-Other Divide Melts
There are two experiences in human life that reliably dissolve the boundary between self and other: sexual ecstasy and psychedelic states. Both produce what researchers call "boundary dissolution" — a softening or complete collapse of the felt sense of where "I" end and the world begins.
Traditional Sleep Remedies: Ancient Wisdom Across Healing Cultures
Long before polysomnography, melatonin supplements, and cognitive behavioral therapy, human cultures worldwide developed sophisticated approaches to sleep promotion rooted in empirical observation accumulated over millennia. Ayurvedic medicine classified insomnia according to doshic imbalance...
Psychosis vs. Mystical Experience: When the Boundary Dissolves
