We are what we think, all that we are arises with our thoughts," said the Buddha, "with our thoughts, we make the world." In other words, you are constantly creating your circumstances by the way you think. It's as if you had a guided missile in your unconscious that relentlessly directs you towards its target, and the target is whatever your thoughts dwell on. Think doom and gloom, and that's what you'll get. Focus on happiness and optimism, and they're already yours. Negative thought frustrate the universal forces that can create a happy, healthy and successful life. They keep our true potential trapped in a mental prison of our own making.
~ Brahma Kumaris, Mt Abu.
