"When we speak of nature, we mean the expression in this world of certain fundamental truths. Nature is a level of truth that is manifested in the world around us. All around us we can see the cycles of nature: the four seasons, the stages of life from birth to death, the rising and falling of phenomena, the movement of thought from one instant to the next. All of this is natural. All of this is part of the process of life. Life is a condition of nature just as nature is a condition of life. Life is created in nature, it develops in nature and it affects nature in ways that cannot be easily described."
