I used to be a big fan and raja yogini. And it is an intellectually deeper system than most western religions I agree. However all those millennia of Vedic knowledge did very little to improve science, technology, or the actual physical well being of humanity. In the end is it more well developed mystical thinking requiring no proof except the purported proof if one becomes a full yogi and devotes years or decades to reaching samadhi and has good enough karma. Difficult to falsify the fundamental assumption of Primacy of Consciousness.
