Andal was found in the gardens of Periazhwar (Vishnuchittar) under the basil plant. She was always Krishna conscious from her childhood days and grew up listening to Periazhwar’s Krishnaleela. She was also know as Kothai (Godha). She used to get up early in the morning with periazhwar and would pluck flowers and make garland.
Andal thought if she can be an ideal bride for lord and wore the garland made for god and would look her reflection in the well. As days passed god lord revealed himself in the well along with Andal and disappeared before periazhwar arrived. One day the lord made sure that periazhwar notice this and periazhwar was disheartened at this sight and informed Andal not to repeat this again and he didn’t send the garland to temple.
Lord appeared in Periazwar dream and declared that he liked only the garland worn by Andal. From this day onwards Andal is called as Shudikudutha Nacchiyar. As days passed Andal loved Krishna like gopi’s and started Kathyayini Vrata in Marghazhi, same as Gopi’s in Dwapara Yuga.
Each of the days Andal sang in praise of Krishna collectively known as Thiruppavai. Andal has sang these songs at her 5th year. Periazhar being her guru it is no surprise that Andal was able to in her childhood days.
