“All who live must die”, but we can prolong life and increase its quality by the simple application of the law of karma. Skillful acts produce beneficial results, and these results are of the same quality as the acts that produce them.
Sparing and protecting the lives of other sentient beings is a simple, effective, and compassionate practice that will result in the extension of life for ourselves and for those to whom we dedicate our merit.
The most straightforward method of ‘saving lives’ is to avoid killing sentient beings, directly or indirectly through our consumption of animals and animal products, whether for food, fashion, or “scientific” research. We can also abstain from killing insects and participating in sports and entertainment activities that harm other beings, such as hunting or staging fights among dogs or other animals. Any effort in this direction, however small, will result in a considerable reduction of the harm inflicted on other sentient beings, and extend our lives and those of others.
Of course, it is best to abstain from participating in the slaughter of animals all together, adopting a vegan lifestyle which eschews the consumption of meat, fowl, fish, eggs, and dairy products, as well as the use of furs, leather, skins, feathers, and other animal products. However, reducing our consumption of animal products for one meal per day, one day per week, one week per month, or one month per year is a good start.
Make a vow, according to your capacity and inclination, and dedicate the merit to all sentient beings, or to specific persons. The life you save may be your own.
