Swami Sivananda Giri hosts “Meditative Living,” and over nearly two hours he let me range across the whole territory: why I left California in 1970 to look for real authority, the five gurus who initiated me, the magic I witnessed at the dhunis of the old Babas, and the way the speech of the marketplace has crept into our own mouths. It is one of the fullest conversations I have given — nine parts, one long evening near Shivarātri.
