This world belongs to God and is therefore not meant for our selfish gratification.
“The false concept of separation from the Lord is described in the Eleventh Canto of the Bhāgavatam (11.2.37): bhayaṁ dvitīyābhiniveśataḥ syād īśād apetasya viparyayo ’smṛtiḥ. Although all existence emanates from the Absolute Truth, Kṛṣṇa, we imagine a “second thing,” this material world, to be entirely separate from the Lord’s existence. With this mentality, we try to exploit that “second thing” for our sense gratification. Thus the psychological underpinning of material life is the illusion that this world is somehow separate from God and therefore meant for our enjoyment.
It is ironic that the impersonal philosophers, in their radical renunciation of this world, claim it to be utterly false and totally separate from the Absolute. Unfortunately, this artificial attempt to divest this world of its divine nature, or, in other words, its relation to God, does not lead people to utterly reject it but rather to try to enjoy it. While it is true that this world is temporary and thus in one sense illusory, the mechanism of illusion is a spiritual potency of the Supreme Lord. Realizing this, we should immediately desist from any attempt to exploit this world; rather, we should recognize it as God’s energy. We will actually give up our material desires only when we understand that this world belongs to God and is therefore not meant for our selfish gratification.”
