Ultimately, we have just one moral duty: to reclaim large areas of peace in ourselves.

Etty Hillesum

While enduring the horrors of a concentration camp in 1943, Dutch author Etty Hillesum wrote these profound words in her diary. As she ruminated on the vital importance of remaining present in each day and banishing the worries of tomorrow from her spirit, Hillesum realized that the only thing we have control over is our own minds. If we can find peace within, we can make a difference in the lives of those around us.
