Well, Kriya, as they say, is par excellence. Controlling the energy in the spine is one of the fastest (if not the fastest) way to self-realization. Learning Kriya and practicing it every day has been a blissful experience. Even simple techniques like Hong-Sau taught during earlier phases are quite powerful even if they don’t seem at first!
Where did you learn Kriya from? Self-Realization fellowship or Ananda? Or perhaps somewhere else?
