و درود خدا بر او فرمود: سینه خردمند صندوق راز اوست، و خوشرویی وسیله دوست یابی، و شکیبایی، گورستان پوشاننده عیبهاست. Amir al-Mu'minin, peace be upon him, said: The bosom of the wise is the safe of his secrets; cheerfulness is the bond of friendship;…

وَ قَالَ (عليه السلام): صَدْرُ الْعَاقِلِ صُنْدُوقُ سِرِّهِ وَ الْبَشَاشَةُ حِبَالَةُ الْمَوَدَّةِ وَ الِاحْتِمَالُ قَبْرُ الْعُيُوبِ.وَ رُوِيَ أَنَّهُ قَالَ فِي الْعِبَارَةِ عَنْ هَذَا الْمَعْنَي أَيْضاً الْمَسْأَلَةُ خِبَاءُ الْعُيُوبِ وَ مَنْ رَضِيَ عَنْ نَفْسِهِ كَثُرَ السَّاخِطُ عَلَيْهِ.

Amir al-Mu'minin, peace be upon him, said: The bosom of the wise is the safe of his secrets; cheerfulness is the bond of friendship; effective forbearance is the grave of short-comings. It is narrated that Amir al-Mu'minin said in expressing this meaning that: Mutual reconciliation is the covering for short comings; and he who admires himself attracts many opponents against him
