The name Kadigachalam came as the Lord gave darsan to the Saptharishi to a kadigai time and gave mukthi. He also gave darsan to Prahalatha by changing his figure of Terror and in the yoga stage. Lord Anjeneya who is in the yoga stage helped Indrathymna Maharaja in killing the Arakkan Nikumban and saved his country. It was held on Sunday and hence evey Sunday is an important one for Siriya Thiruvadi. People take a bath in the Chakkra Theertham of the small hill and worship the Lord.
In Karthigai sundays people pray Lord after taking bath in the Chakkra Theertham and by lying down on its steps. People belive that Lord come and fulfill the wishes of the devotees in their dreams.
