The stanzas from the Periya Tirumozhi of Tirumangai Azhvar, in praise of Lord Narasimha at Ahobilam are recited in this temple. Hence, the temple is considered as a sacrosanct.
The festivals organized in the temple reveal the enduring religious tradition of India. The religious tradition of the temple is continuing its worship for approximately a thousand and four-hundred years, and continues to draw multitudes of devotees even in the present day.
