The spirit of Narayana was in which the Ultimate soul is installed. So on the other hand Vaikundar was viewed as Narayana, the Murthi Stage (i.e. the God with supreme consciousness). A verse in Akilam states that ""The day on which Narayanar came as Vaikundar."" Also as soon as the Santror was born, "(see:Santror Pirappu)" the Seven Virgins felt that they had lost their purity. They tried to assemble the Ganges (water) into a ball, but cannot. They not even look the face of their sons. They started performing austerity that Narayana who was the one who deceived them should marry them, and rule the world along with them. This was accepted by Thirumal. And for this reason Vaikundar marry the Seven Virgins during his Avatar. This is the part at which Ayya Vikundar is highly focused as Narayana in Akilam.
