Thiru Aadi Pooram is a very important festival for Iyengars during the month of Aadi. GODDESS ANDAL’S birthday falls on the pooram star in the month of Aadi. The festival on this day THIRU AADI POORAM is celebrated on a grand scale in Srirangam and Srivalliputhur.
ANDAL is one among 12 Azhwars who are the most famous devotees of Lord Vishnu and authors of Naalayira Divya Prabhandham – “4000 verses in praise of LORD VISHNU”.Head over here for more Gyaan on Azhwars. One day PERIAZHWAR (one of the azhwars) found ANDAL in his nandavanam (garden) near a TULSI (Holy Basil) plant. The day was of Star Pooram (name of star in Indian astrology) in the month of Aadi (according to the Tamil Calendar). So this day is celebrated as ANDAL’S birthday.
Andal wanted to marry Lord RENGANATHAR (Vishnu at SRIRANGAM). She has composed a number of paasurams (devotional songs/poetry) in praise of Lord Renganathar. Her paasurams are THIRUPPAVAI ( 30 Paasurams) and NACHIAR THIRUMOZHI (143 Paasurams).
Suja at The Divine Mother has given more information on Andal here.
THIRU AADI POORAM is celebrated with grandeur at SRIVALLIPUTTUR , the birth place of Aandal, situated in Tamizh Nadu near Thenkasi. This festival will also be celebrated for 10 days at SRIRANGAM. On the 10th day the THIRUKKALYANAM (marriage) of ANDAL and LORD RENGANATHAR is celebrated.
It is a belief that if unmarried girls pray to Goddess Andal on the 10th day (i.e. THIRUKKALYANAM DAY), they will get married soon.
So we all celebrate this Thiruaadi Pooram by preparing sweets and praying to ANDAL.
Akkaravadesil (a traditional rice pudding made in temples) is supposed to be the favourite sweet of Lord Renganathar. We can prepare this on Aadi Pooram.
We’ll post the recipe soon.
