Lecture by Swami Tattwamayananda. In order to cross over the ocean of our accumulated tendencies, vrittis, Patanjali says we must practice Vairagya, dispassion. Vairagya comes with a realization of the impermanence of sensory enjoyments as well as a positive refinement of all our tendencies toward something higher. By the repeated practice of Vairagya, our mental blocks and negative tendencies are weakened and our mind begins to flow towards wisdom. Repetition leads to Viveka, discerning wisdom. How can we repeat such a difficult activity for a long time and without interruption? Only through a sense of sanctity and sincerity – Shraddha. I.2, I.12, I.14
