Imam Ali (AS) said, Serving the soul means protecting it from [unlawful] pleasures and acquisitions, training it with knowledge and wisdom and making it strive in performing acts of worship and obedience, for in this lies the salvation for the soul.
الإمامُ عليٌّ (عَلَيهِ الّسَلامُ) : خِدْمَةُ النَّفْسِ صيانَتُها عَنِ اللَّذّاتِ وَ المُقْتَنَياتِ وَ رِياضَتُها بِالعُلُومِ وَ الحِكَمِ وَ اجْتِهادُها (إجْهادُها) بِالعِباداتِ وَ الطّاعاتِ وَفِي ذلِكَ نَجاةُ النَّفْسِ
