It is necessary... that advancing Knowledge should base herself on a clear, pure and disciplined intellect. It is necessary, too, that she should correct her error sometimes by a return to the restraint of sensible fact, the concrete realities of the physical world. 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. And it is certainly the fact that the wider we extend and the surer we make our knowledge of the physical world, the wider and surer becomes our foundation for the higher knowledge...
This world is a beginning and a base
Where Life and Mind erect their structured dreams;
An unborn Power must built reality.
A deathbound littleness is not all we are:
Immortal our forgotten vastnesses
Await discovery in our summit selves;
Unmeasured breadths and depths of being are ours.
