Nidhi
Nidhi (Sanskrit: निधि, romanized: nidhi) is a Sanskrit term meaning, "treasure". It is generally used to indicate the nine treasures called navanidhi (Sanskrit: नवनिधि, romanized: 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.
