According to Osho, mushrooms (like LSD) are real substances but the 'enlightenment' they seem to produce is a false samadhi—a chemical disturbance of the body, not a transformation of consciousness. No external agent—drug, diet, fasting, breathwork, or posture—can awaken you. Consciousness is pure witnessing, beyond chemistry; only inner awareness and understanding bring genuine awakening.
Mushrooms may cause big, flashy feelings, but they only change your body for a while; real enlightenment comes from quietly watching within, not from taking something.
