Mantraraja

(“king of mantras”) Name given to a
particular eight-syllable mantra associated with the god Vishnu, in which
he is addressed as Narayana. The
mantra itself is “Om Namo Narayana”
(“Om, homage to Narayana”). This
mantra is particularly important in
the Shrivaishnava religious community, which developed in southern
India in the twelfth century. The
mantra is especially associated with
the community’s founder, Ramanuja.
Faithful recitation of this mantra is
said to bestow residence in Vishnu’s
heavenly abode, Vaikuntha.
