A. C. Bhaktivedanta Swami Prabhupada Quote

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.
