There was once a philosopher King, Yoga Narendra Malla, who believed that he was immortal. So, to convince people about his belief he installed a statue of himself in front of his palace. The statue had a Naga forming a canopy over his head and a bird on top of the Nagas head, which looked as if it was about to fly. The statue was devoted in prayer to Taleju, the Goddess of Patan state. Then the King proclaimed that as long as the bird perched on top of the Naga, his subjects should know that hew was still alive.
One day the King disappeared mysteriously. The statue prayed to Taleju and the bird had not flown away. Thus, once a year there is a big festival at which the golden window of his palace is left open in the hope of his return. A dish of meal is also served for him regularly.
