"Flowing with nature, finding the eternal Nature is based on harmony and it finds its balance through the harmonious functioning of its many parts. That which obstructs nature brings trouble to itself as it forces the basic harmony of life to decline into discord. The ancients used to say, "To oppose the flow of nature is to be mentally ill." Greed, anger, ignorance, pride, doubt, and jealousy are all mental defilements that run counter to the flow of nature; they always cause more problems than they solve and they usually lead us only deeper into error. Defilements like these are a kind of excess or a mistaken corrective that rebels against the natural flow of life. If we hoard our money, then we will never put it to good use. If we squander it, then eventually we will be left with nothing more than the stale memory of our profligacy."
