Srimad Bhagvata Mahapurana: Book 10: Chapter 51: Verses 1-14
(Kalayavana gets burnt and) King Mucukunda glorifies the Lord
Sri Suka began again : The Yavana (Kalayavana) beheld Sri Krsna fully emerged (from the city gate) like the rising moon-most charming to look at, dark brown (of hue), clad in yellow silk, with a white curl of hair (known by the name of Srivatsa) on His bosom and His neck adorned with the brilliant Kaustubha gem; endowed with four massive and long arms and eyes ruddy as a fresh-blown lotus, and wearing a lotus-like face, ever full of excessive joy, with beautiful and splendid cheeks and a bright smile and adorned with brilliant alligator-shaped ear-rings. Concluding from the characteristics pointed out by Narada that this most handsome man with four arms and lotus-like eyes and distinguished with the mark of Srivatsa and adorned with a garland of sylvan flowers must be Sri Krsna (son of Vasudeva) and none else, and resolving that since He was armless and was gowing on foot, he (too) must encounter Him unarmed (and unmounted), the Yavana pursued Him with intent to overtake Him while He was running fast with His back turned against him although He is not within easy reach even of those adept in Yoga.
The king said : What was that man called, who killed the Yavana (thus), 0 holy Brahmana, and to whose race did he belong ? What (kind of) prowess did he possess in reality ? Wherefore did he go to sleep in the (said) cave and whose seed was he ?
Sri Suka replied : Born in the race of Ikswaku and an eminent son of Mandhata, he was known as Mucukunda and was not only (supremely) devoted to the Brahmanas but true to his promise (too).
