Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
After purifying the seven planets near Dhruvaloka [the polestar], the Ganges water is carried through the spaceways of the demigods in billions of celestial airplanes. Then it inundates the moon [Candraloka] and finally reaches Lord Brahma’s abode atop Mount Meru.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
We should always remember that the Ganges River comes from the Causal Ocean, beyond the covering of the universe. After the water of the Causal Ocean leaks through the hole created by Lord Vamanadeva, it flows down to Dhruvaloka (the polestar) and then to the seven planets beneath Dhruvaloka. Then it is carried to the moon by innumerable celestial airplanes, and then it falls to the top of Mount Meru, which is known as Sumeru-parvata. In this way, the water of the Ganges finally reaches the lower planets and the peaks of the Himalayas, and from there it flows through Hardwar and throughout the plains of India, purifying the entire land. How the Ganges water reaches the various planets from the top of the universe is explained herein. Celestial airplanes carry the water from the planets of the sages to other planets. So-called advanced scientists of the modern age are trying to go to the higher planets, but at the same time they are experiencing a power shortage on earth. If they were actually capable scientists, they could personally go by airplane to other planets, but this they are unable to do. Having now given up their moon excursions, they are attempting to go to other planets, but without success.
