According to Osho, kundalini is the innate life-energy that surges through the body like racing electrical currents. When permitted to flow freely—without suppression or control—it cleanses body and mind, sometimes erupting as spontaneous cries or movements. Blocking this current creates disturbance; total acceptance and openness allow the energy to purify and harmonize you.
Kundalini is your natural inner power; let it move and express (even as shaking or shouting) so it can clean you, instead of trying to stop it.
