The Punarjani Guha, in Palakkad district, is a natural tunnel 15 meters long in the rocky cliff. It is situated 2 km from the Thiruvilwamala Temple. The chief presiding diety is Sri Rama. The idol is believed to be ‘swayamboo’ ie. born on its own. It is believed that by performing ‘noozhal’ or crawling through the tunnel from one end to the other will wash away all of one’s sins and thus attain rebirth. Only men are allowed to do the ‘noozhal’ and women can only visit the cave. This ritual is practised only one day in a year on Guruvayur Ekadashi.
