This book is a chronicle of a personal search for spiritual enlightenment. John Mucai starts by finding out what religion means. He then looks at the different religions and zeros in on five major ones, namely, Christianity, Islam, Hinduism, and Buddhism. These religions have a combined following comprising about 80% of the world's population. He looks at their beliefs, practices, and sacred texts. And most importantly, the many hard questions that emerge from the texts. While the book would be of immense interest to theologians, it is not a book on theology. Instead, it is an attempt by the author to seek spiritual enlightenment by sifting through the religious literature freely available to any ordinary citizen of the world. The author's findings are illuminating and should hopefully give believers and non-believers a new perspective on religion.
