Nidhi
Nidhi is a Sanskrit term meaning, "treasure". It is generally used to indicate the nine treasures called navanidhi belonging to Kubera, the god of wealth. According to tradition, each nidhi is personified as having a guardian spirit, with some Tantrikas worshipping them. The nature and characteristics of nidhis have remained largely unexplained and have not been fully understood.
