Bhagavatapurana 3.27.26

3.27.26

evaṃ vidita-tattvasya prakṛtir mayi mānasam /
yuñjato nāpakuruta ātmārāmasya karhicit //

25—26. Just as sleep is a source of many evils to one that is not awake and the same sleep cannot tend to the delusion of one who is wide awake; so Prakriti works no evil to him who has understood the truth and who sets his mind upon Me and finds delight in the Atman alone (self).
