8. When intelligence thus perceives this divine light, it is impossible
to discern whence this light comes, from within or from without; for
when it has ceased shining the subject first thinks that it came from
within, and later that it came from without. But it is useless to seek
the source of this light, for no question of location can be mooted
in connection with it. Indeed, it could neither withdraw from us, nor
approach us; it merely appears, or remains hidden. Therefore it cannot
be sought; we must restfully wait till it appears, while preparing
ourselves to contemplate it, just as the eye awaits the rising of
the sun which appears above the horizon, or, as the poets say, which
springs up from the ocean.
