"Efforcez-vous de maintenir en vie dans votre poitrine cette petite étincelle de feu céleste appelée conscience."

Simplified Meaning:

It's important to always listen to that inner voice that tells you right from wrong. This inner voice, or conscience, helps guide your actions and decisions, making sure you stay true to your values. Think of it like a tiny flame inside you that glows brighter when you do good things and dims when you make bad choices. Just as you need to take care of a fire to keep it burning, you need to pay attention to your conscience and act according to what it tells you. For example, if you see someone drop their wallet, your conscience will remind you that the right thing to do is to return it, even if no one is watching. Keeping your conscience active means doing the right thing even when it's hard, and it helps you become a better person. The more you listen to and act on your conscience, the stronger and more reliable it will become. In life, this practice builds trust and respect with others, and it helps you lead a life that you're proud of.
