The Alchemy of Happiness: [Original version] - Softcover

The book was originally written by Imam Ghazali in Persian. It is a compendium of some chapters of his main work "Ihya' `Ulum al-Din". If one consults the corresponding chapters in the Ihya', one would find that many of the arguments presented here also discussed there in details.

Al-Ghazzali in Arabic or Ghazali in Persian and known as Algazelus or Algazel to the Western medieval world, was a Persian theologian, jurist, philosopher, and mystic. Al-Ghazali has been referred to by some historians as the single most influential Muslim after prophet Muhammad. Within Islamic civilization he is considered to be a Mujaddid or renewer of the faith, who, according to tradition, appears once every century to restore the faith of the community.His works were so highly acclaimed by his contemporaries that al-Ghazali was awarded the honorific title "Proof of Islam" (Hujjat al-Islam). Others have cited his opposition to certain strands of Islamic philosophy as a detriment to Islamic scientific progress, although he argued for the separation of philosophy and science.[20][page needed][21][better source needed] [22] Besides his work that successfully changed the course of Islamic philosophy—the early Islamic Neoplatonism that developed on the grounds of Hellenistic philosophy, for example, was so successfully criticised by al-Ghazali that it never recovered—he also brought the orthodox Islam of his time in close contact with Sufism. It became increasingly possible for individuals to combine orthodox theology (kalam) and Sufism, while adherents of both camps developed a sense of mutual appreciation that made sweeping condemnation of one by the other increasingly problematic.
