Unlike many of the books on spiritualism, the present work has a special feature of its own. Its pages do not narrate the tales of ghosts and other supernatural beings, as one in most cases finds in such books that claim to unveil the world beyond the grave. The treatment of the subject is purely a scientific one, and it has taken a new departure from the prevailing methods and systems of presentation of this subject. The present work has given an impartial or dispassionate view on spiritualism showing wisely and ably its merits and demerits, its bright and dark sides as well. All problems of soul, preexistence, immortality, reincarnation and eternality have been clearly solved by the Philosopher-Saint Swami Abhedananda in these lectures in a remarkably lucid and characteristic style of his own. Spiritualism, in these lectures, has never been upheld, nor totally denied. One, going through these lectures, realizes to what extent spiritualism should be accepted and to what extent it ought to be rejected.
