"When we are pure in our deeds, speech and thought, even for a second, all the deities, the gods, and the guardian angels will support us. At that moment, the entire universe belongs to us and supports us, and the throne is there for us to reign upon."
Not killing or otherwise harming other living creatures is of obvious benefit for them. Less obvious is the fact that refraining from harming others is equally advantageous for ourselves. Why? Because of the law of karma. "As ye sow, so shall ye reap." When you kill, or cause others to kill for you, in order to satisfy your desire for meat, you incur a karmic debt, and this debt must eventually be repaid.
So, in a very real sense, the keeping of a vegetarian diet is a gift which we give to ourselves. We feel better, the quality of our lives improves as the heaviness of our karmic indebtedness diminishes, and we are offered entrance into new subtle and heavenly realms of inner experience. It is well worth the small price you have to pay!
The spiritual arguments against eating meat are convincing for some people, but there are other compelling reasons for being a vegetarian. All of them are rooted in common sense. They have to do with issues of personal health and nutrition, ecology and the environment, ethics and animal suffering, and world hunger.
