Julius Evola (The Yoga of Power: Tantra, Shakti, and the Secret Way)
"In regard to hatha yoga, one of the first applications of this instrument concerns one's own body. The goal is to gradually acquire a subtle perception of it and of the forces acting in it. One of the misunderstandings that the yoga practiced in the West has generated is to believe in the existence of physical methods leading to spiritual realizations. This is absolutely preposterous; when the Hindu texts speak about the physique, they are actually referring to something very different from what our contemporaries, especially modern Europeans, mean by that term."
