Vaishravana is the son of Garamdargo
Doniddakpo (stong pa nyid dakpo or Lord of Emptiness, Kubera in Sanskrit) or All-hearing One.
Vaishravana is depicted in a serene countenance with one golden yellow
beautiful face, two mudras, holding Treasure Dhvaja or Victory Banner in his
right hand and a mongoose ejecting jewels from its mouth in his left hand and
sitting with his legs half-folded or pendent on the back of a snow lion. He’s
the Lord of Wealth and Treasury and is depicted with his eight attendants.
It’s a tradition to depict the four
Mahakalas, the red, blue, yellow and white-colored wrathful patron deities on the gates of
Buddhist temples and monasteries or on Buddhist sutras. The yellow-colored
wrathful patron deity is the Vaishravana, the son of All-Hearing One, who is to
protect the treasury and the wealth.
