Worship of God as Mother is an ancient practice in India. Though the references to the Mother-cult are very meagre in the early Vedic literature, we have plenty of material in the later purāṇas and tantras. One of the most famous texts of the Mother-cult, which is very popular in South India is the Lalitāsahasranāma, which again is a part of the Brahmāṇḍapurāṇa. The most celebrated commentary on this text is the Saubhāgyabhāskara of Bhāskara-rāya-makhin (also known as Bhāsurānanda-nātha). He lived during the 17th-18th centuries. His spiritual preceptor was Narasiṁha Adhvarī who taught him 18 kinds of sciences. An adept in several fields like the Vedānta, Mīmāṁsā, vyākaraṇa (grammar) and mantraśāstra (science of mantras) he is said to have composed 42 works. The works Varivasyā-rahasya and Setubandha along with the Saubhāgya-bhāskara are considered as the ‘prasthānatraya’ or the three basic texts of Śrīvidyā, the Mother-cult of South India.
