Srimad Bhagavatam Canto 10, Chapter 24, Text 37

 SB 10.24.37

eso ’vajanato martyan
 kama-rupi vanaukasah
hanti hy asmai namasyamah
 sarmane atmano gavam
 
Translation: 
 
“This Govardhana Hill, assuming any form he wishes, will kill any residents of the forest who neglect him. Therefore let us pay our obeisances to him for the safety of ourselves and our cows.”
 
Purport: 
 
Kama-rupi indicates that the form of Govardhana can manifest as poisonous snakes, wild animals, falling rocks and so on, all of which are competent to kill a human being.
 
According to Srila Sridhara Svami, the Lord presented six theoretical points in this chapter: 1) that karma alone is sufficient to determine one’s destiny; 2) that one’s conditioned nature is the supreme controller; 3) that the modes of nature are the supreme controller; 4) that the Supreme Lord is simply a dependent aspect of karma; 5) that He is under the control of karma; and 6) that one’s occupation is the actual worshipable deity.
 
The Lord presented these arguments not because He believed them but rather because He wanted to stop the impending sacrifice to Indra and divert it to Himself in the form of Govardhana Hill. In this way the Lord desired to agitate that falsely proud demigod.
