Bajra / Vajra dhatu mandala
As soon as you reach the top of the 365-long stairs we can see an impressive gilt vajra borne on the east side, on top of a smooth base of gilt copper, representing the dharmadhatu in the form of the mandala of Manjushri. In Mahayana, there is a big importance of Bajra. Bajrayan is named after Bajra which is an important branch of Mahayana. The Mandala depicts twelve animals representing the 12 months. The animals and birds of the astrological cycle on the pole are: birds, bulls, dogs, tigers, horses, rabbits, lightning, monkeys, mouse, pig, snakes and sheep are engraved. King Pratap Malla placed a stone lion on the right and left side of it. It was placed there by the king of Kathmandu Valley Pratap Malla. He also built other two shrines and the eastern stairway on the premises in the 17th century.
