These prayers are used in daily pūjā, a service of devotion honoring Sri Swami Satchidananda, Integral Yoga founder. At Chidambaram (the Mahasamadhi Shrine of Sri Swamiji), the pūjā is offered to the Sivalingam (according to Tamil Saiva tradition, Sri Swamiji's root tradition). In Sanskrit, Siva means “auspiciousness,” and lingam means “sign” or “symbol.” The Sivalingam symbolizes the Absolute God, the nameless and formless One.
