The 18 Siddhars

The Siddhars by their spiritual and yogic practices attained immense knowledge and experience in Vaithiyam (Medicine), Vatham (Alchemy), Jothidam (Astrology), Manthirigam (Thanthric practices), Yogam (Meditation and yogic exercises) and Gnanam (Knowledge about the Almighty).

 Siddhars believed in a holistic concept.  Accordingly they said

“Food is Medicine, Medicine is Food” (Unave Marunthu, Marunthe Unavu)

“Sound mind makes the sound body” (Manamathu Semmaianal Manthiram sebika vendam)
