Explanation: Siddhas attitude against idol worship and their stress on yoga and right conduct distinguished them from the Bhakti cults.

• They believed in the oneness of the transcendental being (monotheism) in the world as well as in charity towards men.
• The Siddha saints were mostly Shaiva, 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.
