The Yantra is a geometric symbol existing in the external world as well as a subject to be internalized within human consciousness. Kali is the Hindu Goddess of time, of change. She is the power of action, of the breath and of transformation (kriya-shakti). Kali’s essence is Divine Love. Through time, breath and Divine Love all things are accomplished. If we surrender to Her essence, She creates the energy and all is possible. The Kali Yantra, then, contains within it the transformative energy of change.
