jātaḥ kariṣyati surair api duṣkarāṇi
vādair vimohayati yajña-kṛto ’tad-arhān
śūdrān kalau kṣiti-bhujo nyahaniṣyad ante
It is understood that in this verse the description of the Lord’s appearance in the Yadu dynasty refers to the appearance of both Kṛṣṇa and Balarāma, who together removed the demoniac rulers who were burdening the earth. Śrīla Jīva Gosvāmī has pointed out that the description of the incarnations to deal with śūdrān, or low-class men, refers to both Buddha and Kalki. Those who misuse Vedic sacrifice to engage in gross sense gratification, such as the sinful killing of animals, are certainly in the category of śūdra, as are the so-called political leaders of Kali-yuga who perform many atrocities in the name of state management.
