According to Osho, kundalini is not inherently a serpent-like movement; 'serpent power' is a symbolic metaphor born of ancient Indian familiarity with snakes. Awakening will be felt through symbols natural to your own culture and psyche. The reality is beyond imagery; valid symbols are those that are experientially real for you.
Kundalini doesn’t have to feel like a snake; you’ll sense it in whatever images and feelings are real in your life.
