"En teoría, existe la posibilidad de la felicidad perfecta: creer en el elemento indestructible dentro de uno y no esforzarse hacia él."

Simplified Meaning:

This quote is about finding true happiness by believing in something deep inside yourself that can't be destroyed but not constantly trying to achieve it. Imagine you have a treasure hidden inside you, a special quality or strength that makes you feel content and happy. To truly be happy, you need to trust that this treasure exists. But if you spend all your time and energy trying to reach or improve it, you might miss out on actually enjoying your life. For example, consider someone who always wants to be perfect at their job. If they believe they have the skills they need and stop pushing themselves too hard, they might find more joy and balance in their work. It's about having confidence in your potential and being satisfied with who you are now, rather than always chasing after perfection.
