Without correct understanding then one places too much belief in things, and it is not very good

And because when they have no belief in anything, that can be very dangerous. That can destroy the good seeds, many good tendencies. But with that kind of understanding, that kind of believing in Buddha, at least one is keeping good motivation, one is fixing one’s mistakes, easier than without understanding anything. Still, a lot of people have blind faith. Having too much faith or not clear faith, that can be also not good, maybe dangerous as well. Therefore, we have to develop faith through one’s own knowledge or understanding. Without correct understanding then one places too much belief in things, and it is not very good. Therefore, you take opportunities to study as much as you can. The purpose for us to study Dharma is to really have a clear understanding.
