A seeker wrote,

I am not even aware of the method of seeking islah effectively. 

Sayyidi wa sanadi Mufti Mohammad Taqi Usmani (Allah protect him) replied, 

‘Read about the praise-worthy (fadhail) and blame-worthy (razail) morals from Maasir al Hakim al Ummat or Tabligh-e-Deen (of Imam Ghazali, Allah have mercy on him).  Then do your own analysis (are they present or lacking in my character). Wherever you have suspicion ask about it. This is the effective way of seeking islah.’
