I do not see any reason why animals should be slaughtered to serve as human diet when there are so many substitutes. After all, man can live without meat. It is only some carnivorous animals that have to subsist on flesh. Killing animals for sport, for pleasure, for adventures, and for hides and furs is a phenomenon which is at once disgusting and distressing. There is no justification in indulging in such acts of brutality . . . Life is as dear to a mute creature as it is to a man. Just as one wants happiness and fears pain, just as one wants to live and not to die, so do other creatures.
As a Buddhist, I view death as a normal process, a reality that I accept will occur as long as I remain in this earthly existence. Knowing that I cannot escape it, I see no point in worrying about it. I tend to think of death as being like changing your clothes when they are old and worn out, rather than as some final end. Yet death is unpredictable: We do not know when or how it will take place. So it is only sensible to take certain precautions before it actually happens.
