Siddhi Lakshmi, the Accomplished Auspicious One.
This unusual white goddess is the patron deity of the Malla Kings of the Kathmandu Valley and their descendents (13th to the 18th century). Associated with the Secret Black Mother tradition (Guhya Kali), her principal function is to turn back evil along with malicious spirits and negative forces. Also practiced in Bengal, she arises from the Sanskrit literature of the Jayadrataya Mala Tantra.
Multi-headed and multi-armed, brandishing weapons, white in color and peaceful in appearance, her two feet are gently supported by her subservient and dutiful consort, Shiva.
