During the routine, it is difficult to remember the exceptional. To remember it, the mind seems to require silence and solitude. So it easily forgets it, and if it does not make a daily effort to preserve its image, it only becomes aware of it in unexpected, detached, disconnected moments, wasting the bulk of the benefits of its perception. But it is fortunate that the memory comes back and generates a new surprise: in this way the hope is renewed that, this time, it will not be allowed to fade away.
