How does W. Somerset Maugham use imagery in The Razor's Edge?

Imagery:

"I'm like a lost soul in this great city."

"He said that the world isn't a creation, for out of nothing comes, but a manifestation of the eternal nature; well, that was all right, but then he added that evil is as a direct a manifestation of the divine as the good. They were strange words to hear in that sordid, noisy cafy, to the accompaniment of dance tunes on the mechanical piano."
