Between 550 and 300 BC, a Tamil Shaivite Siddhar named Bogar, Bhogar, or Boganathar lived. He was Kalangi Nathar's disciple. He was born near the Palani Hills in Vaigavur. He was educated by his grandmother and mother, both of whom are mentioned in numerous traditions and texts. In his book "Bogar 7000," Bogar himself talks about where he came from. This is also mentioned in Bogar's book Bogar 7000, which he wrote while teaching about enlightenment while traveling from Tamil Nadu to China. Under the sanctum of the Palani Murugan hill temple, Bogar is said to be in "nirvikalpa samadhi." Bogar taught meditation, alchemy, yantric designs, and Kriya yoga at the Kataragama Murugan shrine, inscribing a yantric geometric design etched onto a metallic plate and installing it at the sanctum sanctorum of the Kataragama temple complex.
