الزُّهْدُ أنْ لاتَطْلُبَ المَفْقُودَ حتّى يَعْدُمَ المَوْجُودُ
Asceticism is when you look for something only after you lack it.
من زهد هانت عليه المحن
Asceticism helps you bear disasters easily.
The Imam says that asceticism (which is avoidance of worldly pleasures) helps you manage your way through tragedies and life trials easily. This is because ascetics are emotionally less attached to worldly pleasures and therefore have a strong foundation of patience and inner strength.
