“That infinite world is a subtle world and does not reveal itself openly—yet look how wonderfully it makes its appearance here! Don’t you see how the spring breeze becomes visible in the trees and grasses, the rose-beds and sweet herbs? Through the swaying of fields and flowers you witness the beauty of spring. But when you look upon the breeze itself, you see nothing. This isn’t because the beauty of those rose-beds are outside the reality of the breeze, for the spring breeze contains images of swaying rose-beds and sweet herbs, but those images are subtle and invisible. Only through some medium are they revealed out of their subtlety.”
