They believe that being a monk is the way to liberation. Because they think that the nature of life is ephemeral anyway. So, give them place and respect, give way when they walk. Do anything in your respectful way. And they meditate a lot more. They truly keep the precepts. They truly understand why they became monks and nuns, why they practice. I just respect them because of the ideal they hold, the renunciation they make, the self-denial that they try. They try hard to be a good person, to be a good monk.
