There is a Lord Vishnu temple outside his temple.  Deities as Sastha, Karuppasami, Kannimar, Vinayaka, Muruga and Azhagar Perumal have their shrines here.  Panasal River flows close to Veerappa Ayyanar temple.  As the river originates from a hill, the water pure and sweet.   The beauty of nature with tall trees and plants around the place, make the environment very pleasant.

The Allinagaram village committee is managing the temple.  Soothsayers are there in the temple complex.  The soothsayer not simply predicts future but also offer suggestion to come over problems.  There is also a belief among the people here that after darshan in the temple, they should directly go to their homes only without entering into houses of others on the way, as the benefit of worship would be lost to them.

The villagers pray here for child boon, for timely marriage, for profit in business, relief from debt burdens and problems in life.

Sri Veerappa Ayyanar is a swayambu which is growing in size.  This is evident from the fact that the gold crown and the gold belt made years ago are not fitting now.  Traders in Theni choose this temple for opening their annual new account pujas.   People throng this temple not only for worship but also as a tourist spot with their friends and relatives.

 The idols are made of stones as people believe that stone has a better magnetic power than metals.  Stones contain air, fire, water and also the earth.  Panchaboodhas – five powers – inherent in stone, hence, it is chosen for making idols, say devotees here.

There is also a darga nearby.  People of this place worship here too on Fridays and other important days offering agarbathi (incense sticks) worship.  The place is an example for promoting communal harmony.

A miracle happened about 300 years ago.  People were grazing their cattle in the western ghat regions then.  Despite good grazing, the cows did not give any milk to the owners.  They began to take the milk at the very place whey they were grazing.  One day, while returning home, they fell down on the way with the bowls and heard sounds of someone drinking the milk.

 People of the village gathered at the spot where they fell on first day of Chithirai (about April 14).  One man got possessed and said “I am Veerappa Ayyanar hiding here to protect all of you, bring me out” according to a hearsay story.  The swayambu appeared on this day.  People believe that Veerappa Ayyanar is patrolling in this are during he nights as thry hear the sounds of horse steps.  Ayyanar in the sanctum sanctorum of the temple is in Linga form.  People desirous to see Ayyanar on a horse, made one with long moustache and placed it before the temple.  As Akasha Ganga is good for abishek to Swayambu, the temple has no roof above Ayyanar.  The tradition still continues.
