The Smarta tradition (Sanskrit: स्मार्त, IAST: Smārta) is a movement in Hinduism that developed and expanded with the Puranas genre of literature. It reflects a synthesis of four philosophical strands, namely Uttara Mīmāṃsā, Advaita, Yoga, and theism. The Smarta tradition rejects theistic sectarianism, and is notable for the domestic worship of five shrines with five deities, all treated as equal – Ganesha, Shiva, Shakti, Vishnu and Surya. The Smarta tradition contrasted with the older Shrauta tradition, which was based on elaborate rituals and rites. There has been a considerable overlap in the ideas and practices of the Smarta tradition with other significant historic movements within Hinduism, namely Shaivism, Brahmanism, Vaishnavism, and Shaktism.
The Smarta tradition developed during (early) Classical Period of Hinduism around the beginning of the Common Era, when Hinduism emerged from the interaction between Brahmanism and local traditions. The Smarta tradition is aligned with Advaita Vedanta, and regards Adi Shankara as its founder or reformer. Shankara championed the thesis that ultimate reality is impersonal and Nirguna (attributeless) and any symbolic god serves the same equivalent purpose. Inspired by this belief, the Smarta tradition followers, along with the five Hindu gods, include a sixth impersonal god in their practice. The tradition has been called by William Jackson as "advaitin, monistic in its outlook".
