" Who has made this rainbow, moreover with all its seven colours? There is no authority that is the creator. In fact, all this comes together as a result of 'scientific circumstantial evidences'; it is a natural occurrence. Even a million years ago, it had seven colours, and at present too, it has seven colours. No other changes have occurred. "

― Dada Bhagwan , Aptavani-2: What is Spirituality? (in Gujarati)
