How does Nikos Kazantzakis use imagery in Zorba the Greek?

Examples of Imagery:

"I'm a Sinbad the Sailor... I don't mean that I've wandered all over the world; not at all! But I've robbed, killed, lied, slept with heaps of women and broken all the commandments. How many are there? Ten? Why aren't there twenty, fifty, a hundred? So I could break them all? Yet, if there is a God, I shan't be afraid to appear before him when the time comes."

"[... ]there are three kinds of men: those who make it their aim, as they say, to live their lives, eat, drink, make love, grow rich, and famous; then come those who make it their aim not to live their own lives but to concern themselves with all men - they feel that all men are one and they try to enlighten them, to love them as much as they can and do good to them; finally there are those who aim at living the life of the entire universe - everything, men, animals, trees, stars, we are all one, we are all one substance involved in the same terrible struggle. What struggle? ... Turning matter into spirit."
