Silence of the speech for Sibley is not good. Once in a while it's good because we speak more than necessary. Madman Gandhi is to observe one day of silence in a week. Swami Ranganathanandaji, the 13th president of our order, is to observe silence on Thursdays. So silence of the body of speech, also mind.
In this series of talks, Swami Sarvapriyananda unfolds the highest truths of Vedanta through the study of the Bhagavad Gita (The Song of God).
