Understanding rarely comes in the moment; it comes when the mind is ready to look back. The learners here act without grasping what they are part of, and only later, when love is fully seen, does the meaning of everything fall into place. This is how the deeper lessons work within a mind: they are lived before they are understood, and their sense arrives only when fear has given way and a clearer sight can read the whole.
So a mind need not reproach itself for not comprehending at first. The recognition it lacks is not withheld forever but waits for the readiness that love brings. When the true teacher is finally recognized, the past reorganizes itself around that light, and what once seemed random is seen to have been meaningful all along.
The disciples: the parts of the mind still learning, acting within a truth they cannot yet understand
Jesus glorified: love fully recognized within the mind, the light by which everything before it is at last understood
