No doubt that there are many paths to activation and awaken. But, no one has a market on knowing what is best for anyone. And, if you enter the experience with a pure intention, and approach with sacredness, then most any path can open to you. Don't believe what anyone says about Psilocybin or Ayahuasca might be doing to you regarding auric shells and all that. That's usually FUD coming from someone who is just repeating something and not speaking from their own experience. Can Ujai breath help activate kundalini? Yes. Can Psilocybin also work? Yes. If you are too cautious to experience it your self, or are not called, but are curious, then you better open your eyes, find out who Baba Ganesh was, John Allegro, Jan Irvin ('Astrotheology'). Then think about why cows are venerated, why Krisha and Shiva and many others are blue. Hinduism and Yoga source is in sound, breath, and Soma. Don't be naive and assume that the most 'holy' beings were only doing yoga, meditation, or tapas.
