"Much on earth is concealed from us, but in place of it we have been granted a secret, mysterious sense of our living bond with the other world, with the higher heavenly world, and the roots of our thoughts and feelings are not here but in other worlds. That is why philosophers say it is impossible on earth to conceive the essence of things. God took seeds from other worlds and sowed them on this earth, and raised up his garden; and everything that could sprout sprouted, but it lives and grows only through its sense of being in touch with other mysterious worlds; if this sense is weakened or destroyed in you, that which has grown in you dies. Then you become indifferent to life, and even come to hate it. So I think."
Here's the (important) note on this paragraph in my edition: "Victor Terras rightly considers the passage to be 'probably the master key to the philosophic interpretation, as well as to the structure'" of B.K.
Take that as you will. It's also pretty bad-ass.
