Bir-deva son of Nand-Deva and 5th King of the Vikramaditya Dynasty( Lichhavi)
The king used to sit at the window of his palace, and he regularly saw a leprous grass cutter going to cut grass. One day he was astonished to see that very grass cutter going by with his leprosy all cured and looking very handsome. So he asked him how it was that he now looked so well, and the grass cutter, who was called Lalita replied: “Great King! Yesterday I went to the southern side of the Bagamati river into the Lalita wood in order to cut grass. I became hot and went to a place where there was a pind(pond), took off my clothes, stick my carrying pole into the ground, went to bathe. When I came out of the water my leprosy was all gone. The carrying pole was stick and I could not pull it out. I thought it must be siddha.” Being A devoted to Sarveswara, the king had it in mind to establish a city, some time later Sarveswara appeared to him in a dream. He said: “ Oh King! To make the city, cut down Lalita wood in accordance with the 24 element and in the shape of a Sri Yantra and make your minister Lalita the architect.
