Taittiriya Upanisad occupies an unrivalled place in the Divine Tradition of Hinduism.The Upanisad,declares a manifesto upon the "Hindu way of living"."Speak the Truth,Do your Duty.Do not neglect the study of the scriptures.Do not cut the thread of progeny.Swerve not from the truth.Deviate not from the path of good.Revere greatness.""Let your mother be a God to you;let your guest be God to you.Do only actions which are balmeless.Always show reverence to the great." In his commentary on this upanisad,the journalist,the logician,the scholar and the master of English Literature-Swami Chinmayananda is at his best.
