‘Arif billah Hadhrat Dr. Abdul Hayy ‘arifi (may Allah have mercy on him) instructed the seekers,

“Do not be slack in your effort of self-reformation (islah) till you die, as some of the ailments of self (nafs) take many years to be recognized.

Strictly guard your eyes, ears and tongue (from unlawful). These three organs are the source of all worships and transgressions, including the inner praise worthy and blame worthy moral traits. It is of utmost importance to take appropriate care of them by using them in lawful and abstaining from prohibited. 

However, (God forbid) when you slip (do not despair), repent immediately.”
