If you have ever been far away in the forests or the mountains, far away from all population, you will know that there comes, consciously or unconsciously, a feeling of romance. The wind that repeats the sound coming from the trees, the rocks, the murmur of water running - all tell you that they are wanting to get back something that has been lost. This feeling comes to human beings even during the pleasures of everyday life, for then there is a joy that opens up something in them, and then comes this yearning, and this yearning one feels on every side, in the wilderness, in the forest. There comes a feeling of longing, of 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 will certainly feel their restlessness, their searching for that which is lost.
