One of the greatest gifts one can give is the gift of life. And it stands, therefore to reason, that one of the most terrible things one can do is take away a life.
When we take away the life of another, our own life becomes unsure... it is no longer ours alone, it now belongs to the ones we kill as well. And if we are mindful and quiet we can feel the pain and suffering of our victim. If we are truly mindful, truly quiet, we will never kill, we will never take what is most precious to all beings. We will never take away the gift of life.
