One of the precious gems of the Muslim tradition is the chanting of the Names of God. God mentions in the Holy Qur'an, the sacred book of the Muslims, "to Him belongs the Most Beautiful Names, so invoke Him by them." This book examines what is meant by chanting the Names of God, and the importance of and the implication of chanting these Names. The book draws its resources not only from the traditional texts of Islam but from statements and material from those seeking closeness to God and from Non-Muslim sources including those from other spiritual traditions and researchers. In addition to the many spiritual benefits derived from this practice, the book also implies that the benefits may extend to many other aspects of life, including enhanced feeling of physical and mental well-being, and even to the creation of a more peaceful world. Regarding the effect of this practice on the world, the book quotes the following words of Swami Krishnanandaji Maharaj: "It would not be an exaggeration if I say that you will be doing the greatest service to mankind."
