There is only one certainty in existence and that is your own realization, your own seeing. Unless that happens, don’t become contented; remain discontented. Discontentment is divine; contentment through beliefs is stupid. It is through divine discontent that one grows, but it is the path which is arduous. The path of belief is simple, convenient, comfortable. You need not do anything. You have only to say yes to the authorities: the authorities of the church, of the state. You have simply to be a slave to people who are in power.
