In plain words

Wherever there seems to be duality, one thing sees another, smells another, tastes another, speaks to another, hears another, thinks of another, touches another, knows another. But when everything, for you, has simply become the Self — then what would you see, and with what? What would you smell, taste, speak to, hear, think of, touch, know — and with what? How could you know the very thing by which everything else is known? How could you know the knower itself? This Self is 'not this, not this.' It cannot be caught, because it is never caught. It cannot decay, because it never decays. It cannot cling to anything, because it never clings. It is free, untouched by suffering, untouched by harm. It is the knower —

Close to the Sanskrit

Where indeed there is, as it were, duality, there one sees another, one smells another, one tastes another, one speaks to another, one hears another, one thinks of another, one touches another, one knows another. But where, for him, all this has become the Self alone, then by what and whom would one see? By what and whom would one smell? By what and whom would one taste? By what and whom would one speak? By what and whom would one hear? By what and whom would one think? By what and whom would one touch? By what and whom would one know? By what would one know that by which all this is known? By what would one know the knower? That Self is 'not this, not this' — it is ungraspable, for it is not grasped; it is undecaying, for it does not decay; it is unattached, for it does not attach; it is unbound, it does not suffer, it is not injured. [It is] the knower —
