Concerning the concealment, which is a correction, had it not been for that, man would have been unable to attain any perfection, since he would not be worthy of attaining the importance of the matter. However, when there is concealment, the thing becomes important to him. Even though one cannot appreciate the importance as it truly is, the concealment grants it merit. This is because to the extent that one senses the concealment, so a bedding of importance is made within him.
It is like rungs. He climbs rung-by-rung until he comes to his designated place. This means that he achieves a certain measure of importance with which he can at least endure, though His true importance and sublimity are immeasurable, but nonetheless a measure that will suffice him to persist.
However, concealment in itself is not considered concealment. Concealment is measured by the demand. The greater the demand for something, the more the concealment is evident. And now we can understand the meaning of “the whole earth is full of His glory.” Although we believe it, the concealment still fills the whole earth.
It is written about the future: “For I, … will be unto her a wall of fire round about, and I will be the glory in the midst of her.” Fire means concealment. But still, glory is in the midst of her, meaning that then the glory will be revealed. This is because then the demand will be so great, even though there will be concealment then, too. And the difference is that at this time there is concealment, but no demand. Hence, this is considered “exile.” Then, however, although there will be concealment, there will also be demand, and this is what is important—only the demand.
