Dear friend,
Your heart is a polished mirror. You must wipe it dean of the veil of dust that has gathered upon it, because it is destined to reflect the light of divine secrets.
If we take care of the means, we are bound to reach the end sooner or later. When once we have grasped this point, final victory is beyond question. Whatever difficulties we encounter, whatever apparent reverses we sustain, we may not give up the quest for truth.
Never do I argue with a man with a desire to hear him say what is wrong, or to expose him and win victory over him. Whenever I face an opponent in debate I silently pray - O Lord, help him so that truth may flow from his heart and on his tongue, and so that if truth is on my side, he may follow me; and if truth be on his side, I may follow him.
Every moment instructs, and every object; for wisdom is infused into every form. It has been poured into us as blood; it convulsed us as pain; it slid into us as pleasure; it enveloped us in dull, melancholy days, or in days of cheerful labor; we did not guess its essence until after long time.
If language is not correct, then what is said is not what is meant; if what is said is not what is meant, then what must be done remains undone; if this remains undone, morals and art will deteriorate; if justice goes astray, the people will stand about in helpless confusion. Hence there must be no arbitrariness in what is said. This matters above everything.
