"Dans la foi il y a assez de lumière pour ceux qui veulent croire et assez d'ombres pour aveugler ceux qui ne le veulent pas"

Simplified Meaning:

When someone wants to believe in something, they can find enough positive signs and evidence to support their belief. For example, if a person wants to believe in the goodness of people, they will notice all the kind acts around them, like someone helping an elderly person cross the street. This can make their faith stronger, giving them hope and comfort. On the other hand, if someone doesn't want to believe, they can find reasons not to. Using the same example of human goodness, a skeptical person might focus on the negative news stories they see, like thefts or arguments, which can make them distrustful and doubtful of others. So, this idea can be applied to our lives by understanding that our attitude shapes what we see in the world. If we choose to look for the positive, we'll find it and feel more optimistic. But if we focus on the negative, we'll also find that and might become more cynical. By being aware of this, we can decide how we want to view the world, which in turn affects our overall happiness and trust in others.
