Man is not entirely an animal. He aspires to a spiritual vision, which is the vision of the whole truth. This gives him the highest delight, because it reveals to him the deepest harmony that exists between him and his surroundings. It is our desires that limit the scope of our self-realisation, hinder our extension of consciousness, and give rise to sin, which is the innermost barrier that keeps us apart from our God, setting up disunion and the arrogance of exclusiveness. For sin is not one mere action, but it is an attitude of life which takes for granted that our goal is finite, that our self is the ultimate truth, and that we are not all essentially one but exist each for his own separate individual existence.
