bhurlokah kalpitah padbhyam
bhuvarloko ’sya nabhitah
svarlokah kalpito murdhna
iti va loka-kalpana
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Others may divide the whole planetary system into three divisions, namely the lower planetary systems on the legs [up to the earth], the middle planetary systems on the navel, and the upper planetary systems [Svarloka] from the chest to the head of the Supreme Personality.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The three divisions of the complete planetary systems are here mentioned; fourteen are imagined by others, and that is also explained.
Thus end the Bhaktivedanta purports of the Second Canto, Fifth Chapter, of the Srimad-Bhagavatam, entitled “The Cause of All Causes.”
