The Chithirai festival is celebrated in which state of India?

Tamil Nadu
The Chithirai festival is celebrated every year at the Meenakshi Temple in Madurai, Tamil Nadu during the month of April for symbolizing the unity of saivitism and vaishnavism. It does so by re-enacting the wedding of Lord Sundareswarar (Lord Shiva) and Goddess Meenakshi (Lord Vishnu’s sister). The festival includes a procession of Kallazhagar avtar of Lord Vishnu entering Vaigai river. He travels from his abode in Azhagarmalai to get his sister married to Lord Sundareshwarar. This journey from his abode to his sister’s wedding, on a golden chariot, is the legend behind celebrating the Chithirai Festival.
