Dattatreya Siva Baba is an international spiritual leader, humanitarian and scholar-mystic from the Tamil Siddha tradition of southern India. He is an unusual yogi in that he finds no contradiction in living the spiritual and material dimensions simultaneously. He is the author of several books, including Life-Changing Sounds: Tools From the Other Side, Miracles of the Avatar, and One-Minute Guide to Prosperity and Enlightenment, and the DVD program The Grace Light. He joins us today to talk about a major shift in human consciousness that began on July 17, 2008.
