The Siddhar (Tamil: Cittar, singular Citta, from Sanskrit siddha) are saints in India, mostly Shaiva, in Tamil Nadu, who professed and practised an unorthodox type of sadhana (spiritual practices) to attain liberation. A siddha obtains yogic powers called siddhi by constant practice of certain yogic disciplines and tapasya. The siddhars can be compared to mystics in Western culture.
