Reading about nature is fine, but if a person walks in the woods and listens carefully, he can learn more than what is in books, for they speak with the voice of God.
The great work of life is not to save the world but to attain God Realization which, by being in the process of doing so, you have a tremendously powerful and positive effect on the world condition and consciousness.
~ from BODY OF TIME, SOUL OF ETERNITY by Jerry Thomas
