" The touch of Earth is always reinvigorating to the son of Earth, even when he seeks a supraphysical Knowledge. It may even be said that the supraphysical can only be really mastered in its fullness - to its heights we can always reach - when we keep our feet firmly on the physical. 'Earth is His footing,' says the Upanishad, whenever it images the Self that manifests in the universe. "

― Sri Aurobindo
