Yoni Base is for installing a Shivlinga or Bana Linga. The shivling represents lord Shiva, and is usually placed in the yoni. The shivlinga united with the yoni represents the no duality of immanent reality and transcendental potentiality.
There is a large cleft, a yoni in the bedrock moistened by water flowing upward from an underground spring, generally covered by cloths and ornate chunris, flowers, and red sindoor powder. Devotees and pilgrims offer items for worship directly to the goddess, then touch her and drink water from the spring. They then receive a tilak and prasad by the attending priest. After completing darshan, devotees light lamps and incense outside the temple. Like other temples, worship is not considered complete until the temple is circumambulator clockwise.
