This is called a Homa Kund. Twigs from some specific trees ( with medicinal properties) are selected and fire built over cowdung cakes. Offerings are made to the Fire that springs from here ( live coals are placed to assist the flames ) .Prayers are offered. The Lord Ganesha is invoked every morning so that the classes and other activities go off unhindered. Made just by arranging bricks on the floor. There are bricks at the bottom too, so that the ash will not leave a stain on the floor.
The fire had gone out here as the time was past ten in the morning when we went there.
