The Yoga of Knowledge and Wisdom

Krishna describes how those who worship other gods obtain their desires. 'Sa tayā śraddhayā yuktas tasyārādhanam īhate'—endowed with that faith, the devotee engages in worship of that deity. 'Labhate ca tataḥ kāmān mayaiva vihitān hi tān'—obtains the objects of desire, as ordained by Me. This verse shows that Krishna is the source of all fulfillment—even when people worship other gods, it's Krishna who grants their desires. The desires are fulfilled, but they're material and temporary. This connects to verse 7.21's teaching about Krishna granting faith and prepares for verse 7.23 where Krishna will describe where they ultimately go.
