You cannot avoid Nam Pranayama as one of the fundamental components of left-handed Tantric Kriya Yoga. Does it have a specific purpose? It’s not necessary for it to have its own distinct purpose, as it’s part of a larger system—interwoven like a wheel among many wheels.
You can practice it daily as a psycho-physical workout, or you can incorporate it into a deeper learning experience by studying the ancient practices of this nearly extinct Tantric tradition. We’ve spent years developing a one-year training course, the Andhakaara Path to Power. Yes, it’s inspired by Castaneda, but here, the only psychedelic you use is your own body chemistry, along with the absolutely grueling body workouts that may seem pointless at first.
In this example, you can also see how this workstudy training in ancient Tantric Kriya Yoga functions. You receive a PDF with daily and ongoing lessons, and most days include a video. You can reach out via WhatsApp chat any day, and you also get four video calls per month.
