اَلمُصيبَةُ واحِدَةٌ ، وَ إنْ جَزَعَتْ صارَتْ اِثْنَـتَيْنِ
A tragic event is one. If you do not cope with it, it becomes two.
مَنْ لَمْ يَحْتَمِلْ مَرارَةَ الدَّواءِ دامَ ألَمُهُ
He who doesn’t tolerate the bitterness of medicine will have lasting pain.
This (of course) applies to the physical as well as the spiritual dimensions of human existence.
