Sri Isopanisad Mantra 1
īśāvāsyam idam sarvaṁ
yat kiñca jagatyāṁ jagat
tena tyaktena bhuñjīthā
mā gṛdhaḥ kasya svid dhanam
Everything animate or inanimate that is within the universe is controlled and owned by the Lord. One should therefore accept only those things necessary for himself, which are set aside as his quota, and one should not accept other things, knowing well to whom they belong.
