"Una conciencia tranquila hace fuerte a uno."

Simplified Meaning:

When you have a clear conscience, meaning you haven't done anything wrong or have been truthful and fair, you feel strong and confident. Think about a student who has studied hard and prepared well for a test; they enter the exam room feeling ready and calm because they know they've done their best. Similarly, if a person always tries to help others and does good deeds, they don't have any guilt or worry holding them back. They can approach life with a positive outlook because they are proud of their actions. For example, imagine a friend who always keeps their promises. They don’t have to worry about losing trust or feeling ashamed because they’ve done what they said they would do. This makes them feel secure and self-assured. Living honestly and kindly gives you inner peace. When you don’t have any regrets or secrets, you carry less emotional weight and stress. This mental comfort translates into strength, enabling you to face challenges and make decisions with a clear mind and a steady heart.
