Lecture by Swami Tattwamayananda. Posture becomes steady when we keep one transcendental thought, which is beyond body consciousness. Even indirect approval of evil creates mental obstacles in meditation. Each discipline has three stages of practice: beginning, practicing and perfected. The special example of Ahimsa is discussed. Vyasa explains that you will get back what you have given. This thought will protect you from temptation. Verses: II.33, II.34
