The following information is available about Sri Kamalamuni in the book " Bogar 7000 " written by siddhar Bogar.
Song 5729: Kamalamuni was born on the Tamil month of Vaikasi (May - June), his birth star being 2nd part of Poosam.
Song 5725: The siddhar named Kamalamuni belongs to Kuravar social group. He lived for six-eight generations.
Song 5841: Kamalamuni is 4000 years and some 300 odd (days) old. He lived in China for a long time.
However, siddhar Karuvoorar in his book " Vadha Kaviyam " (Song 584) says "Maamuni" belongs to " Kannar " social group. He does not explicitly say "Kamalamuni", but mentions "Maamuni". The author of this article does not understand whether Karuvoorar refers to Kamalamuni or not.
Sri Kalangi Nadhar belongs to Kannar social group. Many people believe that Sri Kalangi Nathar is siddhar Kamalamuni. In the 63 rd song of " Kamalamuni Suthiram 76 ", a line says that " Kamalamuni alias Kalangi ". Hence it can me true that Sri Kalangi Nathar is siddhar Kamalamuni himself.
In " Bogar Janana Sasthra ", it is mentioned that Kamalamuni attained samadhi at Madurai .
Kuravars form the sixth largest social group of population both in Tamil Nadu and in Ramanathapuram district. They make certain household items out of bamboos and palm leafs and sells them to earn their living. They hunt birds and rear country pigs (black pigs) both for their consumption and sale. They also hunt cats from the village side for consumption. Some of them work as fortune-tellers. Since they use the trained Kili (parrot) to predict the fortune of the people, they are also known as kili josiyars. However, they do not go to any other social groups asking for food. This information on Kuravars is taken from the article "Untouchability and Inter-Caste Relations in Rural India: The Case of Southern Tamil Villages" by A. Ramaiah of Tata Institute of Social Sciences, Deonar, Mumbai.
