All of our personal and social problems are rooted in the states of our hearts. Just as the body has ailments that force us to the doctor, the heart also has ailments that should force us to the doctor. Traditionally, purification of the heart was a central focus of Muslim civilization. Manuals, texts, glosses, and commentaries fill our libraries with the strategies, techniques, and methods for purifying hearts. Many Muslims don’t have access to this rich tradition of spiritual healing that could, if rediscovered and used, heal our persons and societies from many of the destructive forces impacting us. This lecture will discuss some of the dominant ailments of the heart and the strategies the Qur’an, the Sunnah, and our tradition provide us with to address them.
