Each one of us is responsible for the whole of humankind. We need to think of each other really as brothers and sisters and to be concerned for each other’s welfare. Rather than working solely to acquire wealth, we need to do something meaningful, something directed seriously towards the welfare of humanity as a whole.
If there is no solution to the problem then don't waste time worrying about it. If there is a solution to the problem then don't waste time worrying about it.
This is my simple religion. There is no need for temples; no need for complicated philosophy. Our own brain, our own heart is our temple; the philosophy is kindness.
