This book is an attempt to relate the birth and growth of this great religion during the first two hundred years of its life through the life-stories of its ten Gurus, i.e., spiritual preceptors. This work claims no originality; everything it contains has been culled from the sources listed at the end. It has been written solely for the young readers in a simple narrative from; but unlike some other such efforts, the present attempt carefully eschews all those elements that may be considered supernatural and miraculous in nature, as the performance of, and belief in, miracles are against the basic tenets of the teachings of the Sikh Gurus.
