According to Osho, the three phonemes of OM tune successive chakras: A vibrates the navel center (hara/manipura), U opens the heart (anahata), M resonates in the head/third eye (ajna); the ensuing silence flowers at the crown (sahasrar). When sounded with clear witnessing, this sequence aligns and lifts prana upward, avoiding hypnotic sleep and ripening the fourth body into wakeful entry toward the seventh state.
Sound A in your belly, U in your chest, M in your head, then be silent—stay watchful so your energy rises instead of drifting into dreamy trance.
