Kalangi Nathar

Kalangi Nathar was an Indian ascetic who belonged to both the natha tradition of northern India and the siddha tradition of southern India. He was the guru of saint Bhogar and was born in Varanasi and belonged to the ancient tradition of nava (nine) nātha sadhus (holy ascetics), tracing their tradition to Shiva.

He is associated with the Kanjamalai hill in southern India and is often referred to us "Kanjamalai Siddhar". He attained mukti on this hill, near Kanchipuram, where his samadhi, now known as the Sidhhar Kovil temple, is still located. The hill is found in Sivathapuram a small village, 12 km away from Salem, India, enroute to Elampillai. The temple is also associated with Kali and Murugan.
