The Eight Syllables of Sri Vaishnavism

Om Namo Narayanaya, homage to Narayana, is the ashtakshara, the mantra of eight syllables, and the central formula of the Sri Vaishnava tradition. Narayana is Vishnu under the aspect of the one who rests upon the cosmic waters and in whom all beings have their ground; the name is glossed in the tradition both as the resting-place of humanity and as the one who dwells in the waters. The mantra is recited as japa and stands at the heart of the school's understanding of refuge (prapatti), the complete self-surrender to Vishnu that Sri Vaishnavism made the core of its path.

In that tradition the eight-syllable mantra is one of three sacred formulas transmitted at initiation, and the theologian Ramanuja is famously said to have proclaimed it from a temple tower to all comers, against the instruction that it be kept secret, accepting the consequences to himself so that others might be saved, a story the tradition tells to express the priority of grace and accessibility over restriction. Whether or not historical, the account captures the mantra's standing as the compressed statement of the school's central conviction.
