Tirukachur is located in Chengalpat, near Chennai.
The temple is praised by saint Sundarar in his Thevaram hymns.
Lord Shiva facing west is a swayambumurthy.
Saint Sundarar after visiting Tirukazhu Kundram came to Tirukachur on his way to Kancheepuram. Due to long journey, Sundarar and his team were very tired and hungry. They stayed here at the temple complex. Lord Shiva came there as an old man and assured them of food and asked them to wait for a while. Sundarar, with due respect to the old man waited.
Lord Shiva – old man – went out with His bowl (Tiru Odu) for begging, gathered food, came back and fed His devotees with Sundarar. Sooner they finished the food, the old man disappeared. Sundarar sang a Pathigam beginning with the line “Mudhu vai Ori Kadhara”.
Irandha in Tamil means begging, hence Lord is named Irandeeswarar having His shrine outside the temple at a distance and the Host Shiva is named Virundhu Itta Easwarar having his shrine in the prakara. Virundhu-hospitality.
