Understand what these fissures (בקיעות, bekiyot “breakthroughs”) signify above. It is not that they broke through once and went out. Here below as well, if the radiant splendor were visible, we would see how the aspect of the soul that is already included in the face to show the state of the soul emits a continuous shine of radiant splendor that breaks through and goes out literally through these apertures.
However, now that the radiant splendor has been concealed, its only visible action is to break through to produce these apertures. And because it comes from the soul, which is now concealed, just as the radiant splendor is not visible on the face, so too what emerges from these fissures and apertures is also not visible. Quite the contrary: on the face there is at any rate the visible facial expression, for the soul has a certain garb, namely the face itself. But coming through the apertures we see nothing at all, because the soul goes out with no garb at all.
