If one says a word to you, you could accept the word calmly, or you could think about it deeply: Why did he say this? What did he mean? Did he mean to belittle me? I cannot keep quiet. Here you have allowed the word to affect you profoundly, and so it became deeply-rooted in you. Therefore, do not ponder daily events in depth; overlook them and allow them to pass by calmly. Only those thoughts which take root in your mind and heart will bother you.

—H.H. Pope Shenouda III, Monastic Treasures for All of Us
