The rays of Sun fall on the Lord in the month of Panguni, March-April.
Generally Lord Vishnu is called Azhagar-handsome, as He is fond of
dressing. Lord Shiva in Mahendrapalli is celebrated as
handsome-Azhagar.
Sri Chandikeswara graces with his consort in the prakara. There is a
separate shrine for Lord Sri Vinayaka with Ragu and Ketu on both sides.
Lord Muruga graces from His shrine with His consorts Valli and Deivanai.
There are shrines of Sri Kasiviswanatha Mother Visalakshi, Meenakshi
Sundareswarar, Bhairavar and Saneeswarar-Saturn, Sun and Moon. There is
no shrine for Navagrahas- 9 planets in the temple.
Those
suffering from the evil results of past birth (poorva janma karmas),
those facing adverse effects due to Sun, Moon aspects in their
horoscopes have a dip in the Brahmma theertha in the temple for
remedies.
As the holy spring is attributed to Lord Brahmma the Creator,
it is the faith of the people that Brahamma would amend the destiny of
the devotee favourably. Devotees also pray for relief from snake aspects and to gain excellence in academic pursuit.
