Bōgar

Bōgar (बोगर, c. 5th–6th c.) was a Tamil Siddhar and alchemist revered as one of the eighteen great Siddhas of the Tamil tradition. He is best known for the Bōgar Saptakandam, a multi-volume compendium covering alchemy, medicine, yoga, and spiritual practice.

Life/History

Little is known of Bōgar’s historical life with certainty. Tamil Siddha traditionsiddha) tradition places him among the earliest practitioners of rasāyana (alchemy) in South India. He is also known as Boganathar, and tradition holds that he was a disciple of the Siddhar Kalangi Nathar, who initiated him into jñāna yoga. He is said to have been born in Palani, Tamil Nadu, and to have traveled widely across India and Southeast Asia studying mineralogy and spiritual disciplines.

Teachings/Contributions

Bōgar’s Saptakandam addresses seven major topics, including alchemical preparation (rasa shastra), spiritual practice, and the transmutation of the body through mineral and herbal substances. Other alchemical compendia in the Siddha corpus, such as the Bogar Kappiyam, are also attributed to him, containing material on mineral identification, medicinal preparation, and alchemical processes. His teachings bridge the gap between material alchemy and inner spiritual transformation, emphasizing that the same substances that heal the body can liberate the mind.

He is traditionally credited with the creation of the navapashanam Murugan idol at the Palani temple — a figure said to be composed of nine poisonous minerals (navapashana) rendered harmless through alchemical mastery. This idol remains a central object of worship.

Legacy

Bōgar is venerated as one of the pillars of the Tamil Siddha lineage. His influence extends into Siddha medicine, alchemical practice, and devotional worship at Palani. Numerous texts in the Tamil Siddha corpus attribute their transmission to him.
