। ॥ १४० ॥
In plain words
It's only through the eye — and, beneath that, through the Self itself — that sun and moon and lamp are even known at all. In fact, even they can't be known by their own light alone.
Close to the Sanskrit
Only through the doorway of the eye, by [the] higher Self, is there the manifestation of these; or rather, even these objects are not known from mere light alone.
