By best-selling Turkish author Harun Yahya. The principal aim of this book is to induce the reader to make a re-evaluation of matters which he may hither to have deemed quite insignificant, but which are actually the most important issues in his life. In the process, he shall have to keep his prejudices in abeyance until he has made a re-appraisal of those standards which till now he has accepted as absolute. (from foreword)
