Buddhism for Today, p63Faith (shin) is the working of one’s emotions, and discernment (ge) that of one’s reason. Though people often say that a religion or faith ought to be believed in instead of argued about, it is very dangerous to believe blindly in a religion without having any knowledge of it. If this religion is a worthless or wrong teaching, blind belief will result in not only ruining ourselves but also exerting an extremely harmful influence on our families and on society in general.
Even if a religion is a good teaching, as long as we believe in it blindly our faith is liable to be easily shaken by circumstances. Let us suppose that one believes that he will recover from a disease or that his circumstances will improve if only he has faith in a particular religion, without understanding its teachings. He does recover from his illness, believing that his cure is due to his religion, but he suffers a relapse and then begins to doubt. Suppose that then his son fails his university-entrance examination; the father forsakes the faith to which he has so firmly adhered regardless of others’ opinions. This kind of thing is a common occurrence.
This kind of faith is not a firm faith in the true sense of the term but merely a narrow faith. A true religion can always be understood through reason; this kind of understanding is called discernment.
