I understood what that meant; it meant in the first place that the teaching of the heart should be assimilated in the heart. The heart is the notebook for it; when it is written in another notebook it will remain in one's pocket, but when it is written in the heart it will remain in the soul. Besides one has to learn the lesson of patience, to wait, for all knowledge comes in its own time. I asked myself further if it was worth while to come to a place after a long journey, and go there every day for six months to hear of nothing but trees and butter. And my deepest self answered: yes, more than worth while, for there is nothing in the whole world more precious than the presence of the holy one. His teaching may not be given in theories, but it is in his atmosphere. That is a living teaching which is real upliftment.
