Vajrayogini, 'Diamond Female Yogi'
The Queen of Dakinis, shown to drink blood which represents the ability to transmute and transform negative actions into positive: anger into clarity, ignorance into wisdom.
She is a Highest Yoga Tantra Yidam, and her practice includes methods for preventing ordinary death, intermediate state and rebirth, and for transforming all mundane daily experiences into higher spiritual paths.
She wears skulls because she dances with death and transformation as naturally as the crone, the goddess embracing the power of the sacred feminine.
Page 19: Magical diagrams, plus four yoni symbols, mark this woman/priestess as a ritual consort of the god Shiva (see trident on forehead); and/or his living representative(s). The two lingams at the bottom, plus the two gandharvas (Skt., centaurs), aim at the yoni; sometimes refered to as mystic mandala. Snakes surrounding her arms, but clearly held in her power, hint at the kundalini; the rise and fall she is in control of. Note the red and white stains.
