The Sanskrit śraddhā is commonly translated as “faith,“ but the Śrī Vaiṣṇava tradition gives it a richer and more precise meaning. In the Bhagavad Gītā (17.3), Bhagavān declares: sattva-anurūpā sarvasya śraddhā bhavati — each being's śraddhā conforms to the quality of their inner nature. Rāmānuja's commentary on this verse treats śraddhā as the fundamental orientation of the antaḥkaraṇa (inner organ) toward what it takes to be ultimately real and ultimately good.
For the Śrī Vaiṣṇava specifically, śraddhā has two interlocking objects: the śāstras (including the Ubhaya-vedānta of Sanskrit Prasthānatrayam and Divya Prabandham) and the Āchārya's word (upadeśam). Śraddhā in the Āchārya means accepting his instruction without mental reservation — not because the disciple cannot question, but because he has verified through experience that the Āchārya's knowledge exceeds his own. Without this faith, the upadesam remains sterile.
The ācāryas distinguish śraddhā from viśvāsa (trust, confidence) and from āsthikya (the general belief that the Vedas are valid). Śraddhā is operational, engaged, and transformative — it is the flame that converts intellectual understanding into lived practice. Piḷḷai Lokācārya notes that a prapanna with genuine śraddhā will naturally avoid bhāgavata-apacāra (offending devotees) and asat-saṃsarga (association with the unrighteous), because his conviction in the śāstra's teaching about the gravity of these faults is unshakeable.
