Vitthalanatha was born around 1516 (between 1515 and 1518), as the second son of the religious scholar Vallabha. His devotees consider him an incarnation of the god Vithoba (Vitthal) of Pandharpur. He was brought up by Vallabha till the age of 15, and after that, by Vallabha's disciple Damodara-dasa. He was proficient in the Vedas, the Brahma Sutra, and the Mimansa philosophy. He studied nyaya at Navadvipa. Religious activities 
After the death of his father Vallabhācārya(c. 1530), Viṭṭhalanātha's elder brother Gopinātha became the leader of the sect. However when Gopinātha died in 1542 with his son Puruṣottama still a minor, Viṭṭhalanātha emerged as the main leader of the religious sect established by his father. Six years later he faced a challenge by Puruṣottam and his family, who was backed by Kr̥ṣṇadāsa Adhikāri, the first temple manager of the Śrī Nāthajī Temple. Kr̥ṣṇadāsa often had controversial relationships with women, and once allowed a wealthy kṣatriya woman named Gaṅgābāī Kṣatrānī to be present during the private offerings of food to Śrī Nāthajī. This was ritually prohibited and Viṭṭhalanātha banned the woman from the temple premises. However in retaliation Kr̥ṣṇadās had Viṭṭhalanātha banned from the temple for a period that would last six months. Viṭṭhalanātha's eldest son Giridhara then petitioned with local Mughal authorities who had Kr̥ṣṇadāsa arrested. However Viṭṭhalanātha demanded that Kr̥ṣṇadāsa be released, and the two reconciled with Viṭṭhalanātha being reinstated as the head of the sect and Kr̥ṣṇadāsa as temple manager. Puruṣottam would later die at a young age. Vitthalanatha propagated the teachings of his father, and established a religious centre at Gokul. Literary works
