The success of the sun’s chariot is due to the conjunction (with Dhruva.) Thus this divine solar chariot moves about in the heaven. The pins of the yoke and axle are on its south. The pair of reins of the yoke and the wheel of this aerial chariot revolve round and round in all directions like the potter’s wheel. The pins of the yoke and the axle traversing about the four quarters revolve round Dhruva by the force of the wind. The reins of that travelling chariot shorten on the Northern orbit and lengthened on the Southern. The pair of reins are fastened to the pins of the yoke and axle and are held by Dhruva, who thus attracts the sun. When the reins are drawn in by Dhruva the sun covers on either side of the line (diameter) 8000 yojanas. When the reins are released by Dhruva the sun begins to move on most swiftly the outer orbits.—50-58.
