No one can find inner peace except by working, not in a self-centered way, but for the whole human family.
Do not suppress it — that would hurt you inside. Do not express it — this would not only hurt you inside, it would cause ripples in your surroundings. What you do is transform it.
To attain inner peace you must actually give your life, not just your possessions. When you at last give your life — bringing into alignment your beliefs and the way you live then, and only then, can you begin to find inner peace.
Unnecessary possessions are unnecessary burdens. If you have them, you have to take care of them! There is great freedom in simplicity of living. It is those who have enough but not too much who are the happiest.
