bhurlokah kham disas tanoh
svarlokas te dvitiyena
pasyatas te svam atmana
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Of these possessions, with one step I have occupied Bhurloka, and with My body I have occupied the entire sky and all directions. And in your presence, with My second step, I have occupied the upper planetary system.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
According to the Vedic description of the planetary system, all the planets move from east to west. The sun, the moon and five other planets, such as Mars and Jupiter, orbit one above another. Vamanadeva, however, expanding His body and extending His steps, occupied the entire planetary system.
