Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
As in an oil-pressing machine, this first axle is attached to a second axle, which is one-fourth as long [3,937,500 yojanas, or 31,500,000 miles]. The upper end of this second axle is attached to Dhruvaloka by a rope of wind.
