आत्मानमन्तत उपसृत्य स्तुवीत कामध्यायन्नप्रमत्तोऽभ्याशो ह यदस्मै स काम. समृध्येत यत्कामः स्तुवीतेति यत्काम स्तुवीतेति ॥ १२ ॥
In plain words
Having at last approached his own self, let him offer praise while steadily contemplating his desire, alert and undistracted. Swiftly indeed will that desire be fulfilled for him, whatever be the desire with which he offers his praise—yes, whatever be the desire with which he offers his praise.
Close to the Sanskrit
Having finally approached himself, he should praise, contemplating his desire, heedful. Swiftly indeed that desire would be fulfilled for him, with whatever desire he might praise—with whatever desire he might praise.
