Shankusthapana: The Shanku & Silver Naga in the Foundation
Shankusthapana Shanku & Naga
The copper shanku and silver naga placed in the foundation — the symbolic anchoring of the structure to its cosmic support.

The shanku and silver naga
The defining act of Shankusthapana is the placing of the shanku — a consecrated peg, often of copper — together with a silver naga (serpent) in the foundation. In tradition, the cosmic serpent Adi Shesha bears the earth; fixing the naga and shanku symbolically pins the structure to its stable cosmic support, anchoring the building for permanence.
