Thayar perumal padaithara or Brahma padaithara ?

Srimate Raamnujaye NAmaha

Thaayar Perummalul Adakame, one half, almost part and parcel of Perumaal. inspearabable..not part of Brahma’s creaiton.

As per thenkalai sampradayam, except Perumal all others are jeevatmas. Atmas are anadi and so Thaayar is also anadi – not created by anyone. But Perumal has given a special place for Thaayar.

Brahma is a post, based on karma, a jeevatma takes that position.
