Lord
Visnu, who is the source of knowledge and transcendental bliss, has assumed the form of
Sisumara in the seventh heaven, which is situated in the topmost level of the universe. All the other planets, beginning with the sun, exist under the shelter of this Sisumara planetary system.
Thus end the Bhaktivedanta purports of the Fifth Canto, Twenty-second Chapter of
Srimad-Bhagavatam, entitled "The Orbits of the Planets."
