Madhvaon Brahma Sūtra 1.3.11

And this support is said to be given by the mere command of the Imperishable as conveyed by the text; for instance, the Briliadaranyaka Upanishad has,” ^ on the command of this Akshara indeed, O Gargi, the sun and the moon stand supported.” (Bri. V. viii. 9). Now this command or ordinance is that of Vishnu only. “ The seven who are endowed with the power of the glorious and worshipped Lord stand appointed in their 'several duties by the command of Vishnu—the seven, who are pregnant with (the principles of) the world (i.e,, who are appointed to produce the things of the world out of given materials),” (Rv. 1.164-36). “ He who sets the world agoing (in motion like a wheel, along with the four and ninety (gods)” (Rv. I. 155-6). “ There is the one ruler (for there is not a second ruler) ; of Him who dwells in the heart I shall here (now, in this chapter) tell you. Not only for thee and myself, O, king, but also for other powerful ones, He is indeed the source of strength.
