The Lord, of the nature of one who rules, Narayana, dwells, finds his standing, in the heart-region of all beings, Arjuna; he is of the nature of the inmost self that is bright, of a purified inner organ, as is seen in the text 'the day and the dark, the day and Arjuna'. How does he stand in them? The Lord says: causing all beings to whirl, as though mounted on a machine, the word 'as though' is to be marked here, as figures of wood and the like are mounted on a machine; standing there, causing them to whirl by maya, by his concealing power.
