As to what is the main object of every soul, that object may be called spiritual attainment. A person may go through his whole life without it, but there will come a time in his life when although he may not admit it he will begin to look for it. For spiritual attainment is not only acquired knowledge, it is the soul's appetite; and there will come a day in life when a person will feel the soul's appetite more than any other appetite. No doubt every soul has an unconscious yearning to satisfy this soul's appetite, but at the same time one's absorption in everyday life keeps one so occupied that one has no time to pay attention to it.
