The extremity of the yoke and the axle of this chariot which has the steed of wind whirls in all directions like a rope fixed to a nail. In the course of Uttarāyaṇa as the chariot moves about in the maṇḍalas the reins increase in size (i.e. are let loose). In the course of the Dakṣiṇāyana, when the chariot moves about in the maṇḍalas the reins are pulled inwards. In either case, the reins are operated by Dhruva and then the sun seated within, moves about in the maṇḍalas.
