I couldn't ever understand the following:There are us, we need to stop sinning, otherwise we'll die. We repent, and we expect to avoid the lake of fire.But there are some of us who abandon worldly life and go to monasteries. They pray for hours, they work harder than us at getting rid of sinful thoughts and emotions. They devote the whole of their lives to it.Why do they do it? Does this kind of devotion give them a better chance? Do we stand a lesser chance?In other words, what's the goal of living in a monastery at all, what kind of advantage does it give to those who do it? It must give them some advantage, otherwise there would be no monasteries. If there's a need for them, there's something important about them. Please somebody enlighten me.
