According to Osho, if the second (etheric/feeling) and third bodies are undeveloped and out of harmony with the first, kundalini or shaktipat can be harmful. The surge of subtle energy amplifies disharmony, creating inner conflict rather than awakening. Preparation means cultivating moment-to-moment bodily awareness so the first body becomes transparent and the subtler bodies attune, allowing energy to rise safely.
Turning on high-voltage energy in an untuned system can burn the wiring—first tune and harmonize your inner bodies.
