About Bogar Siddhar
Bhogar was a South Indian by birth, belonging to the caste of goldsmiths, who became a siddha purusha under the guidance of Kalanginaathar. In Bhogar’s Saptakanda he reveals details of various medicinal preparations to his disciple Pullippani (so named as he is believed to have wandered in the forests atop a puli or tiger) and at every stage he quotes his guru as the authority. Also Pulippani must have been a young man then, as he is often referred to as a balaka.
It is said that as per the last wishes of his guru, Bhogar proceeded to China to spread the knowledge of siddha sciences and strangely enough his journey is said to have been made with the aid of an aircraft; he demonstrated to the Chinese the details of the construction of the aircraft and later built for them a sea-going craft using a steam engine. The details of these and other experi- ments demonstrated by Bhogar in China are clearly documented in the Saptakanda.
Bogar’s guru, Kālāngi Nāthar, is believed to be a Chinese who attained siddhi in South India and thus became included among the Eighteen Siddhars.
The shrine at the top of the hill, though later than the Tiru Avinankudi temple, has overshadowed the older temple in the present century due to its popular appeal. Created by Bhogar, it was maintained after him by sage Pulippani and his descendants almost as their personal and private temple.
Gateway of Earth & Stone
At the top of Palani Hill, near the holy Murugan which Bhogar had crafted from nine poisonous substances, there is an opening in the Earth; it is a hole in the ground; the mouth of a cave which lies below. Bhogar often lowered himself into the Earth, sat in the cave, accessing Life’s hidden secrets. He performed great austerities there, the magnitude of which very few in this modern age can fathom.
There at the opening Bhogar erected a humble shrine to the Great Mother: a few yantras, a couple of five-metal icons baring the form of the Mother and her son Murugan. He worshipped a small emerald lingam there, about ten inches in height. His one and only disciple, Pulipani (perhaps the only one who truly understood the sage), kept him company at the entrance to the underground cavern on the top of Palani Hill.
When Bhogar felt that his outer work was done, he entered the gateway of earth and stone and sat down in the darkness of the cave. Faithful Pulipani heaved a stone slab over the entrance, sealing Bhogar forever in the blackness of his earthen womb.
For thirteen generations Pulipani’s descendants have watched over that stone slab that marks the gateway to the underground chamber. Long ago, Bhogar’s little shrine was set atop that hallowed spot, and even today, is still worshipped by the vigilant sons of the faithful Pulipani. They say that Bhogar is seated quietly in meditation even now; alone in the darkness; watching the slow passage of time.
His breath is still. His mind is quiet, his heart unwavering; but through the dense dark matter of his earthly form stabs the vibrant & relentless flame of the Kundalini Shakti. There he waits…
