Anant Chaturdashi falls 10 days after Ganesh Chaturthi for a reason. On Ganesh Chaturthi, those who believe in it or follow it, invite the god Ganesh into their home for a visit. He is symbolised by a statue and devotees offer prayers during this period. After 10 days, his visit comes to end and prayers are done to thank him for his auspicious visit and all the blessings he bought with him. After that to signify the god Ganesh's departure, you must escort his statue out, amid ceremony and immerse the statue in a body of water with prayers.
