Wisdom is not knowledge, it is conquering the unconscious, it is full of light. Not even islands of darkness are left in it. When your being is full of light, whether you possess anything or not does not matter, you are kingly.
A wise man is naturally kingly. He may be a beggar, but he is still a king. His kingdom is of the within. He has inexhaustible treasures. He has overcome his unconsciousness; that’s what wisdom is.
