There are many precious things in nature and in art, things that are beyond value, yet there is nothing in this world that is more precious than sight, and that which is most precious is insight: to be able to see, to be able to understand, to be able to learn and to be able to know. That is the greatest gift that God can give, and all other things in life are small compared to it. In order to enrich one's knowledge, in order to raise one's soul to higher spheres, in order to allow one's consciousness to expand to perfection, if there is anything that one can do, it is to help oneself in every way to open the sight, which is the sign of God in man. It is the opening of the sight which is called the soul's unfoldment.
