Nagalapuram is a small town in Andhrapradesh, about 70 kms south-east of Tirupathi. This ancient and vast temple was built during the reign of
Krishnadevaraya. He had named this town as Nagamambapuram in memory of his mother
Nagamamba.
The temple spread on a very vast area with grand Gopurams and huge prakaarams. Now the temple is wonderfully maintained by TTD with beautiful gardens along the prakaarams.
The presiding deity is
Sri Veda Narayana Perumal in
Mathsya Avatar along with his consorts
Sri Devi and
Bhu Devi. This temple is called
Mathsya Avataara Sthalam, the avatar (incarnation) which is the first and foremost among 10 Avatars of Lord Vishnu.
According to the legend, a demon king called
Somukasura once stole the
4 Vedas and kept them in his custody under the sea. Brahma, who is the creator, was worried as the whole world cannot function without the presence of Vedas. He went and pleaded to Lord Vishnu to save the Vedas and the universe.
Lord Vishnu, took the avatar in the form of a Fish (Mathsya in Sanskrit), went deep into the sea and fought with Somukasura. Somukasura was defeated in the battle by Lord Vishnu, who brought back 4 Vedas and handed over to Lord Brahma safely. As God saved Vedas here, he is known as
Sri Veda Narayana Perumal. The other deities present here are Lord Ganesha, Dhakshinamurthy, Sri Venugopala Swamy, etc., among many others.
The Speciality of this temple is the
Surya Pooja which happens annually during the temple's Brahmotsavam on Sukla Dwadasi, Trayodasi and Chathurdasi days of Tamil month Panguni which is approximately around the last week of every March.
On these 3 days one can witness the Sun's rays from the horizon, entering the sanctum and falling at the
Lord's Feet on the first day,
Naabhi (Navel) on the second day and
Forehead on the third day, during the sunset, as the Lord here is facing towards west. All this happens not from the ceiling or any opening in the temple, but from the entrance of the temple. The deity is about 600 meters from the main Gopuram entrance and the Sun's rays have to pass through such a distance to fall directly on the deity.
This miracle never happens again throughout the year except these 3 days. This event signifies Sun God's (Surya) Seva to the Lord to warm up his chilled body, as the Lord has been under water for many years during his war against Somukasura.
Also it is still not understood whether it is the architectural or astronomical brilliance by our ancestors, as this has been happening for ages from now. Large numbers of people throng this temple to witness this rare event.
