About Mind machine

A mind machine uses pulsing rhythmic sound, flashing light, or a combination of these, to alter the frequency of the user's brainwaves. Mind machines can induce deep states of relaxation, concentration, and in some cases altered states of consciousness, which have been compared to those obtained from meditation and shamanic exploration. Photic mind machines work with flickering lights embedded in sunglasses or a lamp that sits above or facing the user's head. The user then "watches" with their eyes closed.
