“The infinity of God is not mysterious, it is only unfathomable; not concealed, but incomprehensible; it is a clear infinity, the darkness of the pure unsearchable sea.”

"Anubis" to the Sphinx, in Act 2 of The Infernal Machine (1932); Collected Works Vol. 5 (1948)

As quoted in The Harvard Biographical Dictionary of Music (1996) by Don Michael Randel
Context: Music is a mysterious mathematical process whose elements are part of Infinity. … There is nothing more musical than a sunset. He who feels what he sees will find no more beautiful example of development in all that book which, alas, musicians read but too little — the book of Nature.

Variant: We live on a placid island of ignorance in the midst of black seas of the infinity, and it was not meant that we should voyage far.
