So many different paths; so many different Truths; this is the essential Truth of the Heart Sutra of Zen and Mahayana Buddhism.
See how the Zen tradition ignores Shakti and the energetic experiences, and yet still is okay:
"Our bodies are given life from the midst of nothingness. Existing where there is nothing is the meaning of the phrase, "Form is emptiness." That all things are provided for by nothingness is the meaning of the phrase, "Emptiness is form." One should not think that these are two separate things."
