A minute study of the formation of the sun and its influence in all things of life illuminates us so as to understand the divine Spirit. Heat, gaslight, electric light, coal fire, wood fire, the burning candle, the flame rising from an oil-lamp, all these different manifestations of light have their source in the sun; it is the sun which is showing itself in all these different forms. Often we separate the sun from all other aspects of light. So it is with the supreme Spirit which is manifested in all forms, in all things and beings, in the seen and the unseen worlds, and yet stands remote as the sun stands remote from all other forms of light. The Qur'an says, "God is the light of heaven and of earth" and in reality all forms, however dense they may be, are a certain degree of radiance belonging to that Spirit which is all light. All the different colors are different degrees of that light.
