Kalangi Nathar was born in Kasi (benares). According to Bhogar's poems Kalangi was his father, which would mean that he was from the Porkollar (goldsmith) or the Vishwakarma caste. Boghar glorifies Kalangi in many of his verses. Kalangi and Bhogar were considered to possess an ideal master and student relationship. It is said that they had a mutual spiritual progresses. Kalangi especially took care of the spiritual advancement of his disciple Bhogar and was behind Bhogar's development and innovations.

Kalangi nathar decided to enter into samadhi in seclusion for 3000 years. He summoned bhoganathar telepathically from tamilnadu to china to take over his mission. Bhoganathar traveled by sea, following the trade route. After Kalagi Nathar entered into trance, Bhoganathar assumed his teaching mission to the chinese. Kalanginathar attained the immortal state at the ago of 315.
Kalangi Nathar is often believed to be the same as the saint Kamalamuni. In the 63rd song of Kamalamuni Suthiram 76, a line states "Kamalamuni alias Kalangi".
The following information is available about Sri Kamalamuni in the book Bogar 7000 written by Bhogar.
However, Karuvurar in his book Vadha Kaviyam (song 584) says that "Maamuni" belonged to the "Kannar" caste. He does not explicitly say "Kamalamuni", but only mentions the name of "Maamuni". It is not clearly known whether Karuvurar refers to Kamalamuni or not.
In Bhogar Janana Sasthra, it is mentioned that Kamalamuni attained samadhi at Madurai. It is believed that siddhar Kamalamuni attained samadhi at Thiruvarur.
