"正如充实的一天带来神圣的睡眠，充实的生活带来神圣的死亡。"

Simplified Meaning:

Imagine you have a day where you accomplish all your tasks, do some exercise, maybe help a friend, and spend time with family. At the end of that day, you feel tired but satisfied, and you sleep really well. This is like when you live your whole life working hard, doing good deeds, and making meaningful connections. When it's finally time to die, you can feel peaceful, knowing you've lived a full life. It's saying that being busy with important and rewarding activities helps you feel restful and content both at night and at the end of your life. For example, someone like Mother Teresa, who dedicated her life to helping others, likely felt she had lived a valuable life and was at peace at the end. We can apply this by making sure our days and lives are filled with positive actions and meaningful purposes.
