MahaSiddha Bhogar or Bhoganathar was a great Siddha who lived somewhere between 550 and 300 BCE. Bhogar became a siddha purusha under the guidance of revered Siddha Kalanginathar.

Bhoganathar was an expert in siddha medicine and, in consultation with the revered Agasthya Maharishi and other Siddhas, used several thousands of rare herbs to make Nava Pashanam or nine chemicals. Out of this Nava Pashanam, he proceeded to make one ‘Master Medicinal Compound’ that could cure all ailments by creating an idol of Lord Muruga the primary deity at Pazhani (in Tamil Nadu). The deity of Lord Muruga has this miraculous healing power such that any substance that touches the idol is believed to attract its healing powers.

Abhishekam, or ritualistic bath, to the Pazhani deity, is generally performed using liquids such as milk, panchamritham (a sweet jam-like mixture made from fresh and dried fruits, honey, jaggery, ghee, and other natural substances) among others, becomes a prasada due to the healing powers that they acquire. The idol continues to be venerated by millions of believers and is a tribute to Bhogar's alchemical prowess.
