Yogambara is one of the most popular Yidam deities of Nepalese Buddhists. Yogambara sits on Ardhaparyanka on the moon on a double lotus placed on a lion. Yogambara is blue in colour and is three faced. His principal face is blue, the right white and the left red. He is six armed, and carries the vajra and bell with his two principal hands. He embraces his prajna Jnandakini who is also blue in colour and is bedecked with snake ornaments. In the remaining two hands he holds the breast and the arrow and in the two hands in the left he holds the lotus bowl and bow.

According to the legend, it is said that the deity Yogambara and consort Jnanadakini manifested themselves in the form of Yaksha and Yakshani in Kamarupa in Assam and gave birth to their son Lord Karunamaya whose chariot festival is continuing even today in Patan city. It is said that during the bathing ceremony of Karunamaya, Jnanadakini his mother in Yaksha form, used to come to Lagankhel in Patan and observe the ceremony residing on a tree.
