PURPORT

The polar star of the universe and the circle thereof is called the Sisumara circle wherein the local residential planet of the Personality of Godhead (Ksirodakasayi Visnu) is situated. Before reaching there, the mystic passes over the Milky Way to reach the Brahmaloka, and while going there he reaches first the Vaisvanaraloka, where the demigod controls the fire. In this planet the yogi becomes completely cleansed of all dirty sins acquired while in contact with the material world. The Milky Way in the sky is indicated herein as the way leading to the Brahmaloka, the highest planet of the universe.
