Sufis are the best examples in the world of dependence upon God. One will find numberless examples in the history of the Sufis of how they have practiced that dependence upon God as something spiritual. How have they practiced it? Not only for their food, but for everything in life they have developed dependence in their nature. While everybody has looked for independence, they have practiced quite the opposite, dependence, and the wonderful results that they have achieved by practicing this are worth studying: dependence on life with food and without food; dependence on health while considering it and without attending to it. And in this way they have not only made themselves independent of the world, but they have made the unknown known to them. It is in this way that they have found the nameless, the formless, the unseen, the unknown God. In the terms of the Sufi this is called Tawakul, which means "dependence upon God."
