This earth is higher than all the heavens; this is the greatest school in the universe. - Swami Vivekananda

Where the whole world is awake, the sage sleeps.

33.... Nature’s task is done, this unselfish task which our sweet nurse Nature had imposed upon herself. As it were, she gently took the self-forgetting soul by the hand, and showed him all the experiences in the universe, all manifestations, bringing him higher and higher through various bodies, till his glory came back, and he remembered his own nature. Then the kind mother went back the way she came, for others who have also lost their way in the trackless desert of life. And thus she is working, without beginning and without end. And thus through pleasure and pain, through good and evil, the infinite river of souls is flowing into the ocean of perfection,of self-realisation. *Glory unto those who have realised their own nature! May their blessings be on us all!

Understanding human nature is the highest knowledge, and only by knowing it can we know God. It is also a fact that the knowledge of God is the highest knowledge, and only by knowing God can we understand human nature.
