“As the story goes, Swami Purushottamananda walled off the vast majority of the cave to stop people from disturbing the siddhas (realized or perfected souls) who were, and perhaps still are, sitting back there in their astral (energy-based) bodies, meditating.
“Is this true? I certainly can’t say for sure. However: this cave is the one place I would make sure to go if I ever returned to Rishikesh. It was intense.”
