According to the legend, an astrologer from Bhaktapur predicted that the sand at the confluence Bhacha Khushi and Bishnumati River in Kathmandu would transform into gold at a certain moment, so the king sent a team of workers to Kathmandu to collect sand from the spot at the special hour. A local merchant named Sankhadhar Sakhwa saw them resting with their baskets of sand at a traveler's shelter at Maru near Durbar Square before returning to Bhaktapur.
