The word also appears in other texts. For example, it appears in "Jaiminiya Upanishad Brahmana" section 111.33, where the cyclic rise and setting of sun and world, is referred to as "the music of spheres", and the sun is stated to be "humming the wheel of the world". According to Ananda Coomaraswamy, the roots ""svar"", meaning "to shine" (whence ""surya"" or sun), and ""svr"", meaning "to sound or resound" (whence ""swara"", “musical note”) and also in some contexts "to shine", are all related in the ancient Indian imagination.
