Virudhak is yet another great king of the southern direction. Virudhak resides in the middle of Sumeru mountain. Virudhak rules over a city called Sudarsana located to the south of Sumeru Mountain. The city is extremely beautiful and occupies an area of 6000 square yojanas. Virudhaka leads an assembly of Kumbhandas to serve as the guardian of the Buddha dharma in the southern direction.

In the past Buddha Shakyamuni instructed Virudhaka that he should protect and guard the Buddha dharma in this Jambudvipa where 1,000 buddhas come to bless the sentient beings. In reply to that the great king of Kumbhandas promised to protect and guard the Jambudvipa in the southern direction.

Virudhak body is red in colour. Virudhak shows a wrathful appearance. His right hand holds a sword. His left hand rests on his knee. In Nepalese tradition he is called Khadgaraja and can be seen in the corner of the roof of the temple and also in the entrance of the monasteries.
