। ॥ ४०७ ॥
In plain words
Wise people have always seen this clearly: whatever is superimposed on something is never actually different from what it's superimposed on — just look at the rope mistaken for a snake. The idea that they're two separate things survives only as long as the error does.
Close to the Sanskrit
The non-difference of the superimposed [object] from its substratum has been observed by the wise, as with the rope-snake, etc.; the notion of their difference lives only on error.
