This spiritual guide to the self is a manual of tazkiyah, or self-purification. It does not merely illustrate the maladies of the human spiritual condition: it acknowledges the struggles and insecurities to which we all succumb from time to time, and also offers remedies. The antidotes to our ills come from authentic Quranic verses and hadith (prophetic sayings), which inspire remembrance of the Almighty and His beloved Prophet. This manual, based on the 11th and 12th century works of Imam Abu Hamid Al-Ghazali, the proof of Islam and a great sage of exception, can be adapted to our busy lives in the modern, high-tech era and will be accessible to people of all ages and faiths, believers and non-believers alike.
