The Buddha's doctrine is not negativism. An investigation of the nature of man's soul shows that, while there is no _ātman_ or ego-entity, the very being of man consists in his karma, his deeds, and his karma remains untouched by death and continues to live. Thus, by denying the existence of that which appears to be our soul and for the destruction of which in death we tremble, the Buddha actually opens (as he expresses it himself) the door of immortality to mankind; and here lies the corner-stone of his ethics and also of the comfort as well as the enthusiasm which his religion imparts. Any one who does not see the positive aspect of Buddhism, will be unable to understand how it could exercise such a powerful influence upon millions and millions of people. The present volume is not designed to contribute to the solution of historical problems. The compiler has studied his subject as well as he could under the circumstances, but he does not intend here to offer a scientific production. Nor is this book an attempt at popularizing the Buddhist religious writings, nor at presenting them in a poetic shape. If this _Gospel of Buddha_ helps people to comprehend Buddhism better, and if in its simple style it impresses the reader with the poetic grandeur of the Buddha's personality, these effects must be counted as incidental; its main purpose lies deeper still. The present book has been written to set the reader thinking on the religious problems of to-day. It sketches the picture of a religious leader of the remote past with the view of making it bear upon the living present and become a factor in the formation of the future. * * * * * It is a remarkable fact that the two greatest religions of the world, Christianity and Buddhism, present so many striking coincidences in the philosophical basis as well as in the ethical applications of their faith, while their modes of systematizing them in dogmas are radically different; and it is difficult to understand why these agreements should have caused animosity, instead of creating sentiments of friendship and good-will. Why should not Christians say with Prof. F. Max Müller: "If I do find in certain Buddhist works doctrines identically the same as in Christianity, so far from being frightened, I feel delighted, for surely truth is not the less true because it is believed by the majority of the human race." The main trouble arises from a wrong conception of Christianity. There are many Christians who assume that Christianity alone is in the possession of truth and that man could not, in the natural way of his moral evolution, have obtained that nobler conception of life which enjoins the practice of a universal good-will towards both friends and enemies. This narrow view of Christianity is refuted by the mere existence of Buddhism.
