Nandi Gayatri Mantra

Nandi s the name for the bull which serves as the mount (Sanskrit: Vahana) of the god Shiva and as the gatekeeper of Shiva and Parvati. In Hindu Religion, he is the chief guru of eighteen masters (18 Siddhar ) including Patanjali and Thirumular.[1] Temples venerating Shiva display stone images of a seated Nandi, generally facing the main shrine. There are also a number of temples dedicated solely to Nandi.

The application of the name Nandi to the bull (Sanskrit: vṛṣabha) is in fact a development of recent centuries, as Gouriswar Bhattacharya has documented in an illustrated article entitled "Nandin and Vṛṣabha".[2] The name Nandi was earlier widely used instead for an anthropomorphic deity who was one of Shiva’s two door-keepers, the other being Mahākāla. The doorways of pre-tenth-century North Indian temples are frequently flanked by images of Mahākāla and Nandi, and it is in this role of Shiva’s watchman that Nandi figures in Kālidāsa’s poem the Kumārasambhava.
