When one is in the countryside, when one walks under the trees and feels so close to Nature, to the trees, the sky, all the leaves, all the branches, all the herbs, when one feels a great friendship with these things and breathes that air which is so good, perfumed with all the plants, then one opens oneself, and by opening oneself communes with the universal forces. And for all things it is like that.
