आरोपितं नाश्रयदूषकं भवे -त्कदापि मूढैर्मतिदोषदूषितैः ।नार्द्रीकरोत्यूषरभूमिभागंमरीचिकावारिमहाप्रवाहः ॥ ४९९ ॥
In plain words
Whatever is only superimposed can never actually stain what it is superimposed on - not even when a confused mind swears it is real. The great rushing flood of a mirage never wets the dry, barren ground it seems to cover.
Close to the Sanskrit
That which is superimposed never, even when [imagined] by the deluded whose intellect is corrupted by error, becomes a blemish on its substratum; the great flood of mirage-water does not moisten the tract of barren soil.
