Description in the Javanese wayang retellings: In the wayang world, Batara Wisnu is best known for his incarnations: Rama, [Arjuna_Sasrabahu], Kresna and Arjuna. Kresna is said to be Wisnu's incarnation as thinker and Arjuna is Wisnu's incarnation as agent. There are many other stories in the Mahabharata about smaller incarnations of Wisnu into animals or people in order to rectify a misdeed.
