This work is a valuable contribution to the world's needs in the sphere of physical, mental, and spiritual well-being. It is unique in its scope, as it identifies and recommends what is truly scientific in the causes and treatment of diseases, in addition to emphasizing the prevention of illness. We advise keeping it as a permanent reference book.

And why do we recommend it to the general public? Because of the breadth of its instructions, which are not technical and can be understood by anyone, and because they are so rational that they can be easily followed.
