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.
It is all too easy and too simple to disdain as "superstition" everything one cannot understand, but the ancients themselves knew very well what they meant when they used symbolic language...the Spirit can always come back to breathe fresh life into the symbols and rites and give them back their lost meaning and the fullness of their original virtue.
