Srimathe Ramanujaya Namaha,
Namaskaram Govindan Narayanan Swami,
With Acharya ThiruvAdi Bhalam & Velukkudi Swami’s Aasrivadham,
Regarding devareer’s 1st query “……………………..But i am missed to understand how shiva part of thiruvattaru perumal………………“
As said above Sriman Narayanan (Samashti Shristi) created Brahma and inturn Brahma (Vyeshti Shristi) created Rudra as per Srimadh BhagavatAm verses.
Hence, these representations are seen in Anantha Padhmanabha Perumal Temple in Thiruvananthapuram, like from Perumal’s Nabhi Kalama Braham is seen and Shiva Linga in same sanctum.
However in Thiruvatar Adhikesava Perumal Temple, Brahma will not be seen in sanctum, since this Perumal represents HIS presence before HE did the Samashti shristi (before creating Brahma). Then came the later Thiruvanathapuram Anantha Padhmanabha Perumal Temple. So Brahma and Shiva presence in the material world is seen at alater stage.
But why only Shiva lingam is seen in Thiruvatar Adhikesava Perumal Temple and not Braham is due to the Sthala mahatmayam, Shiva is doing Kainkaryam to Adhikesava Perumal, since Shiva is a SriVaishnavaite (devotee) of Perumal as said by Vyasa Maharishi in Srimadh Bhagavatam 12.13.16,
निम्नगानां यथा गङ्गा देवानामच्युतो यथा ।
वैष्णवानां यथा शम्भु: पुराणानामिदं तथा ॥ १६ ॥
nimna-gānāṁ yathā gaṅgā
devānām acyuto yathā
vaiṣṇavānāṁ yathā śambhuḥ
purāṇānām idam tathā
Means:
nimna-gānāṁ yathā gaṅgā : Like how Ganga is the greatest of all rivers.
devānām acyuto yathā : Like how acyuto (Achutha a.k.a SriKrishna) is Supreme Para-Brahmam among All Deities,
vaiṣṇavānāṁ yathā śambhuḥ : Like how amongst the Vaishnavas, Shambhu (Rudra a.k.a Shiva) is a great Vaishnava.
purāṇānām idam tathā : Same way amongst all 18 Puranas, Srimadh BhagavAtam is the Greatest.
Thiruvatar Adhikesa Perumal Sthala Puranam, as how Shiva is doing Kainkaryam to Perumal as below pulled from online Temple website:
Brahma performed a Yaga without Saraswathi Devi and as a result of Saraswathi’s angry, two asuras by name Kesan and Kesi emerged out of the Yagagni (sacrificial fire). They were troubling the three worlds. The Devas approached SriVishnu (Perumal) and requested HIM to find a solution. Lord Mahavishnu in the form of AdhiKesava Perumal fought with Kesan. Perumal threw Kesan who fell on top of Mahendragiri and Perumal blew His conch. Instantaneously, Adhiseshan wound himself around asura Kesan thus disabling the asura to move and immediately Perumal laid on Adhiseshan thus putting His weight. When the asura tried to get out of Adhiseshan’s coils, Perumal made 12 Shivalingams to stand as guard around the asura and Perumal. These famous Shiva Temples are Thirumala, Thikkurussi, Thrupparappu, Thirunandhikkara, Ponmana, Pannippakam, Kalkkulam, Melankodu, Thiruvidaikkodu, Thiruvithamkode, Thiruppanrikkode and Thirunattalam. Even today, the worship to Shiva on Sivarathiri day – The famous Shivalaya ottam – is said to be complete only when the devotee after visiting the 12 Shiva shrines ends his trip in the Perumal Temple.
Kesi who saw her brother defeated wanted to avenge and hence she along with her friend Kothai took the form of rivers and encircled the temple with the intention of submerging the temple. At that time, Bhoomi devi Thayar raised the temple. Hence, the temple is situated at a height of 55 feet from the ground level. The image of the Gopuram clearly indicates this. The rivers joined with Arabian Sea at a place known as Moovaatru mukham. The rivers were warned by Perumal and they repented for their action. Perumal forgave them and had a dip in Moovaatru mukham. Even today, during Painguni utsavam, Perumal comes on golden Garuda and has dip in the river thus enacting the saapa vimochana incident.
Regarding devareer’s 2nd query “…………………….True we shouldn’t focus on demigods focus only sriman Narayanan…….”
This is because, the SriVaishnava’s in one particular Acharya Lineage follow their own Acharya GuruParamparai Shishtacharam, due to which they don’t go and interfere in other devata’s daily routine, since every devata’s or manushya like us is another JeevAthma but in different shareeram’s (bodies) like Deva shareeram or Manushya shareeram, BUT All Jeevathma’s have Praaptham only with the ParamAthma “Sriman NarayanA”. Hence, they don’t focus on others, that doesn’t mean disrespecting other devatas.
