Then there is a joy that opens something in us, then there comes this yearning; and that feeling one feels on every side in the wilderness, in the forest. There comes the feeling of longing, the deep yearning of the heart, the searching for something that has been lost. When we look at the beings living around us, we see the same thing. For instance, look at the birds and contemplate their restless flight, the ceaseless roaming of animals in the forest. The first thought that might come is that they are searching for food. But he who has a deeper insight into nature certainly will feel the restlessness sooner or later, the searching for that which is lost.
