In the literature of Hinduism, Vinchai are proclamations and instructions to the newly born child Vaikundar, by his father Lord Narayana, also known as Vishnu, one of the three godheads in Akilathirattu Ammanai, the source of Ayyavazhi mythology. Three such Vichais took place during the period of Vaikundar; the first in Thiruchendur, immediately after his incarnation; the venue second and third Vinchais are in Muttapathi (sea), one by one between his incarnational activities.
