Lecture by Swami Tattwamayananda. Pranayama practiced with Yamas, Niyamas, and detachment lead to concentration. Otherwise, it leads to excitement and restlessness. Pratyahara is the ability to withdraw the mind from the senses. When that happens, we are no longer enslaved by the senses. Instead, our mind flows in the opposite direction. One result is we have the ability to concentrate because sense distractions cannot take our mind away. With this kind of concentration on ideas and the corresponding sounds and words, scriptures can be memorized. Verses: II.51, II.52, II.53, II.54
