Ayya Vaikundar (Tamil: அய்யா வைகுண்டர்), according to Akilattirattu Ammanai (or Akilam), a scripture of the Ayyavazhi, was a Manu (father, sovereign) Avatar of Narayana, incarnated as Muthukutty or Mudisoodum Perumal (c. 1810 – c. 1851). He is referred to as Sampooranathevan, a deva (a deity).
The exact date of birth of Mudisoodum Perumal is unknown. It is mostly placed in either 1810 or 1809, while others follow the view of Akilam.
