Thiru Aadanoor. Thirumangai alwar brandishing a sword.

The Moolavar here is known as Andu Alakkum Ayyan. seen in bhujaga sayana pose with his lovely head resting on the Marakkal can said to represent a bushel. He is facing east the Thayar is Kamalavasini and also Bhargavi, Mantrapeeteswari, sri chakra Nivasini. the utsavar thayar is Ranganayaki. surya and chandra Pushkarini. and Pranava Vimanam. god appeared to Kamadhenu, Brighu Maharishi, Agni Bhagvan, and Thirumangai alwar.

In Thiru Aadanoor, Thirumangai alwar has a place within the sanctum sanctorum itself. In very few temples does Thirumangai alwar have a separate shrine for himself. In most temples he is seen with the other alwars  in a mandapam or a niche in the corridor. In Varadaraja Perumal koil in Kanchipuram and at Therezhundur in Tanjore district there are seperate shrines for him. but here in Thiru Aadanoor he is seen in the garbha griha itself and that too brandishing a sword. The story goes that after he spent a lot of time money and effort in renovating the temple at Srirangam he was tired and he spent some time in this village. one day Perumal appeared to him in his dream and said that many who had served him had acquired riches etc but it was rather strange that though he had done so much service to the Lord was not rich. He further said that the next day Thirumangai alwar should go to the banks of Kollidam river and that a person would meet him and confer wealth etc. The next day the alwar along with various others went to the banks of the Kollidam river there they saw a majestic figure standing there with a measuring unit in his hand. On seeing the alwar he gave a bushel full of mud to the alwar. and the moment the Alwar received it it turned to gold. the others watching this also extended their hands to receive their share of the mud. but in their case the mud remained as mud itself. Without realising the significance of what had transpired they rushed on the donor the Perumal in disguise. Thirumangai alwar is said to have brandished his sword to frighten away the disappointed crowd. Hence he is seen here in the Garba griha itself in this attire.

Legend: It is believed that the sage Brigu consecrated the primary deity here. The sage was given a garland by goddess Lakshmi which he gave to Indra. He handed it to his elephant which trampled the garland under his foot. Angered by this act, the sage cursed Indra. Indra sought the pardon of the goddess. Lakshmi said she would be born as Brigu’s daughter and marry the Lord in this place upon witnessing which Indra’s curse would be quashed. According to legend Indra did so and his curse was eliminated. It is widely believed that ThirumangaiyAzhwAr spent all his money in building an outer peripheral enclosure at Srirangam temple. There was no money left to pay the laborers. . The Lord spoke to him to meet him at the KoLLiDam riverbank where he appeared as a merchant with a “marakkAl” (a measuring vessel), a writing implement, and a palm leaf. The merchant told the AzhwAr that Lord Ranganatha sent him there to help the AzhwAr. When the AzhwAr asked for money the merchant said he did not have money but will give a measure of sand to every laborer which would turn into gold for those who did honest work but not for those who did not put in an honest day’s work. It turned out that nobody got gold. They chased the merchant out and he escaped to AthanUr where the Lord shed his merchant identity and revealed himself to the AzhwAr. Then he wrote with the scribe on the palm leaf and handed it to the AzhwAr and preached him. That scene is captured in the idol at the sanctum sanctorum. There is a figure of Vishnu on the vimAnam located amidst the other figures. It is believed that the figure has been growing over time. Now only the knees of that figure are visible. It is believed that when the feet become visible that would be the “end” of the world.

What is Anadhyayanam? During 2 months period starting with the full moon day in karthika month (October~November), up until Hastha star constellation in Pushya month (~January), the 4000 songs of Divya Prabandams are not recited. All the Divya Prabanda recitation service in all Divya Desams (holy lands) will also be stalled during this period. 

Historical facts according to 6000 padi Guruparampara Prabhavam:

Sri Thirumangai Azhwar (Kaliyanâs) period 
Sri Thirumangai Azvar the last of the Azvars gosti was the first Azvar to start this Adhyayana Utsavam. He requested Sri Namperumal of Thiru aRangam Periya Koyil, to hear the thousand verses of Sri Nammazhwar. Thus Sri Namperumal made a sasanam (divine order), asking to bring Sri Nammazhwar from Azhwar Thirunagari for attending 
Thiruvadhyanothsavam (the Festival of chanting the 1000 Thiruvaimozhi). Kaliyan went to Azhwar Thirunagari (Thirukurugur) and brought Azhwar from there to Srirangam and celebrated the adhyayana Utsavam. Namperumal gave His festival of âmanjakuliâ to Azhwar as a reward for fulfilling his divine Order of attending Adhyayana Utsavam. 

Geographically, Srirangam and Azhwar Thirunagari are separated by a lot of distance. Because of that, and various other reasons, this process of bringing Nammazhwar for the Adhyayana Utsavam was stopped sometime after Thirumangai Azhwarâs period.

Svami Nathamunigalâs period
It was only during the Nathamunigal period again the Thiru Adhyayana Utsavam resumed. Nathamunigal made arrangements to bring kaliyan from Thirunagari to Srirangam for adhyayana Utsavam. After Kaliyan's Thirunakshathram is celebrated at Thirunagari, the sasanam (divine order) of Namperumal is announced for all, and all the SriVaishnavas in Thiruvali Thirunagari (the birth place of kaliyan) bring Thirumangai Azhwar to Srirangam. From thereupon, along with Namperumalâs âtholukiniyanâ (palanquin), they go to Azhwar Thirunagari and bring Nammazhwar to Srirangam on the palanquin of Namperumal. 

After 10 day Thiruvaimozhi Thirunal (Adyayanothsavam), Azhwar is escorted back to Azhwar Thirunagari. On the way, Azhwar stops at ThiruTholaivillimangalam divyadesam for his Masi Utsavam and reach his native place later. Kaliyan enjoys the âmanjakuliâ Utsavam in Cauvery and leaves to his native place too. This Utsavam is considered as a combining festival of south and North SriVaishnavas. 

Svami Ramanujaâs period
The distance between Srirangam and Azhwar Thirunagari became a very big problem for the Utsavam and also the fear of thieves became a great treat to SriVaishnavas to do the Utsavam. So, Swami Emperumanar installed Nammazhwar with ANJALI HASTAM (the posture with folded hands) inside the Srirangam temple itself and restarted the Utsavam in the presence of Thirumangai Azhwar of Srirangam.

Namperumalâs desire is to make divya prabandams of Azhwarâs equal in status to Sanskrit Vedas. He wanted the (to recite and not to recite) adhyayanam and anadhyayanam periods to be implemented for dravida Vedam also as for Sanskrit Vedam. Even after emperumanarâs period when there is no need to actually stop chanting divya prabandams, the successive Preceptors decided to observe the that (supposed to be) travel time(roughly 2 months) as anadhyayanam. Hence, no festivals or Thirumanjanams (holy shower) are offered to Perumal during this period.

After the Islamic invasions from the North, Sri Periya Jeeyar (Manava:la ma Ma:munikal)revitalized and revived this Utsavam and increased its popularity many fold. (As per the Thiruvullam Svami Ramanuja). Araiyar Sevais(Singing Dhivya prabhandams using Iyal Isai natakam, abhinayam and using two divine cymbals) in Srirangam, Srivillipuththur, Azvar Thirunagari, Thirukkurungudi are very famous.

Even today, we are supposed to honor the same custom of our Previous Preceptors and act according to Namperumalâs Divine Desire. But this does not affect pasurams in Jeeyar padi (worship procedure graced by Sri Manava:la mahamuni) thiruvaradhanam. Only sevakalam is prohibited. But, in mantra pushpam we drop âsendral kudaiyamâ pasuram and add âemperumanar darisanam yendre idharkuâ pasuram from Upadesarathnamalai. Each Divyadesam has its own date to restart the divyaprabhandhams. But in all houses and aacharyanâs divine mansions, prabandham recitation is resumed only after koorathazhwanâs sathumurai. (Thai (Pushya month)- hastam (hastha star)).

Greatness of Parasara muni.
Parasara Muni had built an ashram and was offering prayers. at about that time the milky ocean was churned and amrutham obtained and distributed amongst the devas and rishis by Lord Vishnu in the Mohini form. Parasara was one of the rishis who obtained a little bit of amrutham for himself. The greatness of Parasara Muni was he wanted to share his portion with his disciples the animals the trees living in his kshetra. seeing him carry the divine nectar Indra warned him and expressed the fear that the asuras may waylay him and grab the coveted prasadam. Parasara succeeded in taking it to his ashram there he mixed it with the water of the tank near by. Later this tank came to be known as Amruthavarthini. later it is known that a severe drought occurred which lasted for twelve long years which was followed by famine too. the only place not to have been affected by the catestrophies of drought and famine was the area of the Ashram. three demons by name Tanjakan, Dantakan and Tarakan with their followers came to know of this and came to the ashram and partook of the waters from the tank. and seemed to have gained back their power. now Parasara approached Brahma and requested for help. he however directed him to Lord Shiva saying he was a creator and that Siva should be approached who advised him to approach Maha Vishnu and that he would send Chandika devi to help them. though Chandika devi was able to let loose her arrows and the asuras fell unconscious the companions immediately revived them by sprinkling the water from the tank on them. when Parasara approached Maha Vishnu, he reminded Parasara about the warning given by Indra however he helped by separating the amrutham from the water. Just like the swan separates the milk from the water. having done that Lord Vishnu decided to deal with Tanjakan and Dantakan and leave Tarakan to be handled by Chandrika devi.

Tanjakan let loose a lot of arrows but they fell at his feet causing no damage, then Tanjakan took the form of an elephant and rushed towards Vishnu with an uprooted tree. the Lord then took the form of Narasimha and just as he was about to tear open his heart the asura pleaded with him for a last wish and of course god conceded he requested that he should be seen in the Narasimha form and continue to stay there secondly the place should be named after him. thus the place was known as Tanjapuri after the deamon in course of time changed to Tanjavur.
Seeing Tanjakan dead Dantakan ran and hid inthe crevices of the earth the lord followed him in the form of Varaha a boar and killed him too.
Chandika Devi Kali succeeded in killing Tarakan and god conferred on her the title Eka Vira.
Parasara Muni was pleased as peace returned to his ashram he prayed god to continue to stay there and the Lord is seen there as Neelamega Perumal.
