Given the scale of life in the cosmos, one human life is no more than a tiny blip. Each one of us is a just visitor to this planet, a guest, who will only stay for a limited time. What greater folly could there be than to spend this short time alone, unhappy or in conflict with our companions? Far better, surely, to use our short time here in living a meaningful life, enriched by our sense of connection with others and being of service to them.
If humanity is to survive, happiness and inner balance are crucial. Otherwise the lives of our children and their children are more likely to be unhappy, desperate and short. Material development certainly contributes to happiness - to some extent - and a comfortable way of life. But this is not sufficient. To achieve a deeper level of happiness we cannot neglect our inner development.
