The very purpose of our life is happiness, which is sustained by hope. We have no guarantee about the future, but we exist in the hope of something better. Hope means keeping going, thinking, ‘I can do this.’ It brings inner strength, self-confidence , the ability to do what you do honestly, truthfully and transparently.
Sensory experience does not offset the intense pain or pleasure we feel on a mental level; it may distract us, but doesn't overcome it. On the other hand, if we have peace of mind, even negative experiences do not upset us. Peace of mind is also good for our physical health. Medical experts have found that anger, hatred and fear eat into our immune system. Being calm and relaxed is better for our physical well-being.
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.
Basically, the Buddhist attitude is that you should not accept certain things through sheer faith. And for that you need a skeptical attitude. Buddha himself made this clear to his followers. He said you should not accept those things I taught out of respect for me, but rather through investigation by yourself.
Now you are on the Buddhist way. Keep up your meditation, as there is no instant illumination. The mind moves slowly into this. Do not become attached to your method. When, in the course of your meditation, your consciousness will have expanded and been transformed, you will then recognize that all the ways are valid ways.
