أَحْيِ قَلْبَكَ بِالْمَوْعِظَةِ وَ أَمِتْهُ بِالزَّهَادَةِ وَ قَوِّهِ بِالْيَقِينِ وَ نَوِّرْهُ بِالْحِكْمَةِ وَ ذَلِّلْهُ بِذِكْرِ الْمَوْتِ وَ قَرِّرْهُ بِالْفَنَاءِ وَ بَصِّرْهُ فَجَائِعَ الدُّنْيَا.
Imam Ali (as):
Revive your heart with exhortations, and kill it will asceticism, strengthen it with conviction, enlighten it with wisdom, subdue it by remembering death, make it acknowledge mortality, make it see the misfortunate of this world.
