Spiritual progress is expansion of the soul. It is not always desirable to live on the top of the mountain, because the ground also is made for man. What is desirable is to have one's feet on the ground and the head as high as the top of the mountain. A person who can observe from all sides, from all angles, will find a different experience seeing from every angle; looking at every side will give him a new knowledge, a knowledge different from what he had known before.
