Path of Yoga Tantra

1. Without practice, there is no Tantra. There is a great deal of difference between giving poses for diving and actually diving into water. I am applying the same analogy to the world of Tantra. Reading and discussing about Tantra is good, but it is not Tantra. Tantra and Yoga are the only Practical Ways of Spirituality that involve action. So, they are called Anusthanik Dharma, Practical Religion. Vedanta is mostly self reflection and analysis. Bhakti yoga is also mostly mental-emotional.
2. Tantra is hands-on sadhana, 100% practical, and one can clearly feel the evolution taking place within. And one must push himself and keep pushing beyond unknown boundaries.
3. Tantra Yoga uses vivid visualization of Chakras (Muladhara to Sahasrara), channels (Susumna, Ida, Pingala nadi-s), Shakti (energy), Bija Mantra, Devata (deity), etc. That is a very scientific form of meditation. So in Tantra, progress is rapid.
4. Tantra requires a Guru, from whom this direct instructions must be received. One cannot do tantra sadhana on his own. The tantra related scriptures have been intentionally written in a complicated, multi-layer-ed manner to thwart casual onlookers and non-believers. So, if the adept master doesn't reveal the secrets of his path, one can easily stray.
5. The Nyaya, Vedanta etc. are descriptive analytical paths that explain and explain, which is like beating around the bush. Tantra and Yoga are direct methods of perception. It's like hitting the nail right between the eyes, spot-on.
