Introduction

One time Swami Ramanujar was going to Thirukkolur. In the outskirts of the divyadesam, a lady came and bowed to him. Swami asked her "From where are you coming?" She replied that she was coming out of Thirukkolur. Upon hearing it, Ramanujar said "Sharing one person's cloth between seven people and eating anything (that is, struggling), everyone tries to enter Thirukkolur, as mentioned by Azhvar - 'thiNNam en iLamAn pugum Ur thirukkOLUrE'. How is it that for you it is a place to leave?" The lady replied "adiyEN nAyanthE-nAyanthE!" and gave the 81 statements called Thirukkolur Ammal Varththaigal.

She then said "If I had the same knowledge as of those mentioned in the 81 statements, then I could stay in Thirukkolur. I do not possess such a knowledge. Does it matter if a rabbit's droppings were in the field or on the side?" She then added "If you were to visit Thirukkolur, then all the festivals of Vaiththamanidhi Perumal and Madhurakavi Azhvar would occur grandly".

Hearing her words, Ramanujar was pleased and visited the lady's home, asked her to cook a meal and ate it (normally this would not be done by a sanyasi) and gave her prasadam and divine water.

This was mentioned by Periya Vanamamalai Jeeyar having heard it from Thiruvaymozhippillai.
