After the Bhattar twins were born, Kooratthazhvan, waiting on his acharya Ramanuja, did not do anything for them such as naming them.

On the 11th day, Ramanuja, delighted that his dear disciple had children due to the blessing of Lord Ranganatha, came to Koortthazhvan's home with his disciples.

Once there, he asked Embar to bring the children to him. As Embar brought the babies to Ramanuja, he kept blessing them by reciting the Dvaya mahA mantra in their ears.

As Ramanuja received the babies in his divine hands, he saw with surprise that they were shining with divinity and asked Embar "I see the fragrance of Dvayam with these babies. How is that?" Embar replied "I was reciting the Dvaya mantra in their ears as protection for them as I brought them to you".

Ramanuja then said to Embar "Since you recited the great mantra in their ears for their protection, you will be their acharya".

Then Ramanuja named the children "Parasara Bhattar" for Parasara Bhagavan and "Veda Vyasa Bhattar" for Veda Vyasa. This completed one of his vows made to Alavandar.
