His wife Ponnacchiyar was so beautiful like a damsel, so that Dhanurdasa never left her and used to gaze at her moonlight beauty always. Once Ponnacchiyar wished to see the Chithra Festival of Namperumal, so Dhanurdasa took her, walking by her side, held his coverlet over her head in great solicitude to screen her handsome face from the sun's rays.

   In Nisuiapuri (Uraiyur) lived a couple named Dhanurdasa (Pillaiurangavilli dasar) and Ponnacchiyar. They belonged to malla cult and he was an excellent athlete and archer. His wife Ponnacchiyar was so beautiful like a damsel, so that Dhanurdasa never left her and used to gaze at her moonlight beauty always. Once Ponnacchiyar wished to see the Chithra Festival of Namperumal, so Dhanurdasa took her, walking by her side, held his coverlet over her head in great solicitude to screen her handsome face from the sun's rays. Shri Ramanuja was returning from his ablutions in Kaveri river surrounded by his disciples to join the procession of Namperumal. As he was coming, he noticed this couple, wondering how love and affection towards a girl can make a man blind, shamelessly transforming this love and affection into a public proclamation. Shri Ramanuja approached Dhanurdasa and asked straightaway why he was doing like this. To this Dhanurdasa  replied, " look at her beautiful eyes Swami, I fell in love with those eyes, I have never seen such a beautiful ones ever". Swami answered "If i show you the beautiful eyes,what you will do?" to this Dhanurdasar replied," I will be forever in your service "Emperumanar caught hold of Dhanurdasa's hands took him to Periyaperumal and requested Periyaperumal to show the full beauty of the eyes. To which Dhanurdasa fell captivated life long. He became one of the prime disciples of Emperumanar. 

   Emperumanar's affection towards Dhanurdasa was so great that we can find, Emperumanar used to lean on Dhanurdasaathi, before going for his bath. While after bathing he used to lean only on Dhanurdasa.

   This love of Emperumanar towards Dhanurdasa made many disciples envious. Hence they complained to Emperumanar. One day Dhanurdasa was summoned to Emperumanar and while he was talking to Emperumanar, Swami instructed those complainers to go in the shadow of the night to Dhanurdasa's home and steal the jewels – ponnachiyar was wearing and come back. The disciples agreed and they left for Dhanurdasa's home,while Dhanurdasa without knowing all these drama stayed back. When the disciples went to Dhanurdasa's home they found Ponnachiyar asleep and they happily started their job. They stole all the ornaments which she was wearing on her one side. While doing this Ponnachiar became awake, but she understood that they were Shrivaishnavas, and she well understood a Shrivaishnava will not do this unless otherwise they were in such a financial distress

   She thought whatever she owned was a Shrivaishnava's property. So in order to make the snatching of the jewels,which she wore on the other side of her body easy, she just turned around as if she was in sleep. Seeing this, the disciples thought she was awake, and they took whatever they stole and ran away to Emperumanar's mutt. Emperumanar seeing his disciples coming back, gave permission for Dhanurdasa to leave, and asked the disciples to follow Dhanurdasa silently. Once when Dhanurdasa reached home he found his wife missing some jewels and to this ponn Achiyar explained the incident. She told they ran away when she turned around. To this Dhanurdasa remonstrated her in the face telling that, you understood Seshathva, but you did not understood the meaning of parathanthrya. If you have laid as if you were a stone, they might have stolen rest of the jewels without any problem. Who told you to turn around and show that you are awake? The Shrivaishnavas were wonderstruck to this and they immediately fell at the feet of Dhanurdasa, and returned the jewels and explained the drama in detail. It is recorded that Dhanurdasa's life was full of such incidents.
