According to Osho, in Dynamic Meditation the early phases use hypnotic energy to stir and break inner dreams and conditioning, but it is safeguarded by witnessing—you stay wakeful, alert, and no one can impose anything against your will. People experience more when they have strong will, intelligence, and courage to let it happen; fear, ego-defense, and dullness inhibit the process.
The meditation shakes up your inner stuff while you stay awake watching; the braver and more attentive you are, the more it works, and fear or resistance blocks it.
