“Let your loyalty to another human being come about in this way: there will be moments — quickly passing by — when he will seem to you filled and illumined by the true, primal image of his spirit.
Then can come, yes, will come, long stretches of time when your fellow-being seems clouded, even darkened. But learn at these times to say to yourself: The spirit will strengthen me; I will remember the true, unchanging image that I once saw. Nothing at all — neither deception nor disguise — can take it away from me.
Struggle again and again for the true picture that you saw. The struggle itself is your faithfulness.
And in those efforts to be faithful and to trust, a human being will come close to another as if with an angel’s power of protection.”
