Monk: My religion would not exist if we monks and priests did not wear robes, and if we did not provide the people with rituals. You shouldn't criticize monks. One becomes a monk to simplify life and create the space to develop one's spirit - a space that would not be there if one was living in the world.
Man: You disappoint me. You have reached the limit of your rationality and are beginning to rave and throw scripted responses at me. Now I feel as though I am talking to a cold unthinking machine rather than a real human being.
You say your religion would not exist without all the robes and rituals. Yes indeed, it would cease to exist; but what have robes and rituals got to do with wisdom? The fact that your religion would disappear without such things shows that your religion is unconcerned with truth.
Regarding your idea about the simple monastic life - come now! Do you honestly think your life, with its unending rules, elaborate rituals, and convoluted rationalisatios, is simple? What you really crave is space to cultivate your selfish happiness unhindered - this is your "religion".
