SB 10.64.32
durjaram bata brahma-svam
bhuktam agner manag api
tejiyaso ’pi kim uta
rajñam isvara-maninam
Translation:
[Lord Krsna said:] How indigestible is the property of a brahmana, even when enjoyed just slightly and by one more potent than fire! What then to speak of kings who try to enjoy it, presuming themselves lords.
Purport:
Even those made powerful by austerity, mystic yoga and so on cannot enjoy property stolen from a brahmana, and what to speak of others.
