The third grave precept is Honor the body—do not misuse sexuality. Honor the body of Nature. When we begin to interfere with the natural order of things, when we begin to engineer the genetics of viruses and bacteria, plants and animals, we throw the whole ecological balance off. Our technological meddling affects the totality of the universe, and there are karmic consequences to that. The three wheels: body, mind and mouth; greed, anger and ignorance are pure and clean. Nothing is desired. Go the same way as the Buddha: do not misuse sexuality.
The fourth grave precept is Manifest truth—do not lie. One of the very common kinds of lying that is popular these days is called greenwashing. Greenwashing is like whitewashing—it pretends to be ecologically sound and politically correct. You hear Monsanto Chemical Company tell us how wonderful they are and how sensitive they are to the environment. Exxon tells us the same thing. The plastics manufacturers tell us the same thing. Part of what they are saying is true. You couldn't have a special pump for failing hearts without plastic. You couldn't have an oxygen tent without plastic. Sure, fine, thank you. But stop making plastic cups and plates that are not biodegradable and are filling up the dumps. Another kind of lying is the lying that we do to ourselves about our own actions. We go off into the woods, and rather than take the pains to haul out the nonbiodegradable stuff that we haul in, we hide it. We sink the beer cans, bury the cellophane wrappings under a root. We know we have done it, but we act as if it didn't happen. Gain the essence and realize the truth. Manifest it and do not lie.
The fifth grave precept is Proceed clearly—do not cloud the mind. Do not cloud the mind with greed; do not cloud the mind with denial. It is greed that is one of the major underlying causes of pollution. We can solve all the problems. We have all the resources to do it. We can deal with our garbage, we can deal with world hunger, we can deal with the pollution that comes out of the smokestacks. We have the technology to do it, but it is going to cost a lot of money, which means that there will be less profit. If there is less profit, people will have to make do with a little bit less, and our greed won't let us do that. Proceed clearly; do not cloud the mind with greed.
