Śrī Vallabhācārya belonged to a Telugu Brāhmaṇa family of Andhra Pradesh. His ancestors, Yajñanārāyaṇa Bhaṭṭa and Gaṇapati Bhaṭṭa were Vedic scholars and Śrautins (performers of Somayāgas) of high repute. They had a prophetic vision that the Lord himself would take an avatāra (incarnation) in his family. Lakṣmaṇa Bhaṭṭa had completed performance of 100 Somayāgas and as a result, Vallabhācārya was born as the second son of Lakṣmaṇa Bhaṭṭa and Yallammagāru. He underwent Vedic and śāstraic studies according to the family traditions and became a full-fledged scholar and later founded the the Puṣtimārga (Bhāgavata Sampradāya) which is known as Śuddhādvaita-darśana.

Vallabhācārya composed a number of books in Sanskrit, some of which are listed below.
