a new exhibit on Tantra, a religious and philosophical movement from India. With a history of nearly 1500 years, Tantra defies simple description, but it often involved horror, shock, pain, sexual passion, and other extreme emotions as ways of reaching the divine. One of the oldest Tantric stories has it that their god Bhairava "decapitated the orthodox creator god Brahma to show the superiority of the Tantric path and used his skull as a begging bowl." Human bones were used in many Tantric rituals, orgiastic sex in others.
And now, of course, Yoga has become a way that middle class women manage the stress of their families and corporate jobs.
Thus the age we live in.
