Namaskaram.
adiyen understand that vadakalai vaishvites perform Para samarphanam after samasrayanam. One of my college mate who underwent these, mentioned that prapanna refers only to those who performed Para samarphanam. Is that so?
Is Para samarphanam not done with thenkalai vaishvites or any other thing is done equivalent to that.
