namah purastad atha prsthatas te
namo ’stu te sarvata eva sarva
ananta-viryamita-vikramas tvam
sarvam samapnosi tato ’si sarvah

"Obeisances to You from the front, from behind and from all sides! O unbounded power, You are the master of limitless might! You are all-pervading, and thus You are everything!"

Arjuna says that the Lord is everywhere around. Without exception, He is pervading in everything. So Arjuna prefers to call Him, Sarva = The Whole. Are not others separate from Him? Yes, all are different from Him, but it is He, Who is the Antaratman in all and controlling and commanding all. Purastad = to [Your, Sri Krishna's] front, nama = [I, Arjuna] salute, atha = also, prsthata = from [Sri Krishna's] behind, namostu te = salute You [Sri Krishna], sarvata = from all sides [salutations], sarva = [the Lord as a] Whole. The Lord is Whole and so Arjuna offers salutations from front, behind and from every side. Ananta-virya = boundless valour, amita = beyond description, vikrama = powerful, sarvam= all in this Universe, including all chetana-achetana [movables and non-movables or, with or without knowledge], samapnosi = pervading [without exception], tata = therefore, sarva = everything [Sri Krishna is]. Earlier Arjuna mentioned the names of certain gods and told that the Lord was all of them. Before that, we also saw that Arjuna mentioned that the Lord was chit, achit, baddha and mukta, etc. Arjuna tells that the Lord is inanimate objects like stone, mud, etc., and also says that the Lord is superior beings like Agni, Vayu, etc. He says lord Brahma also is Sriman Narayana. That is everything from mud, tiny grass to animals, birds, etc., to Devas, is the Lord, Arjuna says. Reason for mentioning that is what Arjuna tells here; that the Lord is pervading all without any exception. We see a pillar made of stone and call it as a stone pillar; a ring made of gold, as a gold ring; a dhoti made of cotton as a cotton dhoti. Since the Lord is pervading all, it is correct to call the pillar as Bhagavan pillar; to call ring as Bhagavan ring; to call a dhoti as Bhagavan dhoti. That is why Arjuna calls everything - Vayu, Agni, Varuna, everything - as He, the Lord. His valour is beyond our imagination. Sri Rama -Sri Vijayaraghava - symbolises valour. When we worship the Lord Utsavar from His front, we see His Abhaya mudra, allaying all our worries and fears. He graces with the left arm firmly holding the mace and with the Consorts. Nearby, yet another Utsavar, without Consorts, is also gracing. 
SECOND UTSAVAR SRI PORERU


This Kshetram is also famous for the 'keel kudhirai' [mechanical horse கீல் குதிரை].
MECHANICAL HORSE VAHANAM

 On the Eighth day of Brahmotsavam, the Lord mounts this Horse. The Horse has many mechanical features, which enable the Horse to make movements; and for the spectator, it would appear as though the Lord was riding a real Horse! On days other than Utsavam day, the Horse is disassembled and kept as Three parts. It is because of the belief that if kept assembled, the Horse might run away! The carpenter who designed and fabricated this Horse dedicated the Horse to the Lord and vowed not to make another for any other temple. When he was forced to make another, he preferred death at His feet. Even today, as a mark of appreciation, the Lord visits the locality of carpenters in this place on Horse vahanam day, before continuing His procession.
THE LORD RIDING THE HORSE

 We also would offer our obeisances to the Lord, on the Horse, from all sides.
