Love, compassion and concern for others are real sources of happiness. If you have these in abundance, you will not be disturbed even by the most uncomfortable circumstances. If you nurse hatred, however, you will not be happy even in the lap of luxury. Thus, if we really want happiness, we must widen the sphere of love. This is both religious thinking and basic common sense.
