The temple is located in a densely populated area of the place.  As the Selva Chintamani tank is close the temple, there is always a cool breeze here.  The temple is in a further down level now than it was earlier, it is said, hence the height of the swayambu idol of Karupparayan also had gone short to simply one foot from the earlier 5.

People pray particularly for protection from accident and physical welfare.  While praying, devotees offer some sacrifices.

There was a resting stone about 100 meters away from the temple, known as Sumai Thangi Kal in Tamil.  People coming from far off places used to place their head loads on this stone and relaxed for a while.  As some began misusing the stone for some wrong purposes, they have made steps of it and continue the use.

The deity was earlier worshipped as the border custodian deity of this place in front of the present Perur temple.  According to some local history, Peruru temple was in a jungle area.  Devotees to Perur temple worshipped Karupparayan for safety.  They also offered the animals they hunted as Padayal to the deity.  The tradition of animal sacrifice to Karupparayan began from this old tradition.  Also they offered the sacrifice even while they were praying to him.  But due to some prohibitory conditions, this is followed only during the Chithirai Thiruvizha occasion only.

It is to be noted that those blessed by Karupparaya Sami are now in Germany, Singapore and other foreign countries.  Failure to celebrate the annual festival results in serious accidents taking place near the temple, says the managing committee of the temple.
