yojanānāṃ sahasrāṇi bhāskarasya ratho nava
īṣādaṇḍas tathaivāsya dviguṇo munisattama //

The chariot of the sun is nine thousand leagues in length, and the pole is of twice that longitude; the axle is fifteen millions and seven hundred thousand leagues long; on which is fixed a wheel with three naves, five spokes, and six peripheries, consisting of the ever-during year; the whole constituting the circle or wheel of time. The chariot has another axle, which is forty-five thousand five hundred leagues long. The two halves of the yoke are of the same length respectively as the two axles (the longer and the shorter). The short axle, with the short yoke, are supported by the pole-star: the end of the longer axle, to which the wheel of the car is attached, moves on the Mánasa mountain. The seven horses of the sun's car are the metres of the Vedas, Gáyatrí, Vrihatí, Ushńih, Jayatí, Trisht́ubh, Anusht́ubh, and Pankti.
