You shall love your neighbor as yourself. Whatever you wish that men would do to you, do so to them. Not one of you is a believer until he loves for his brother what he loves for himself. A man should wander about treating all creatures as he himself would be treated. Try your best to treat others as you would wish to be treated yourself, and you will find that this is the shortest way to benevolence. One going to take a pointed stick to pinch a baby bird should first try it on himself to feel how it hurts. Comparing oneself to others in such terms as "Just as I am so are they, just as they are so am I," he should neither kill nor cause others to kill. One should not behave towards others in a way which is disagreeable to oneself. This is the essence of morality. All other activities are due to selfish desire.
The whole purpose of religion is to facilitate love and compassion, patience, tolerance, humility, and forgiveness.
