It was in 1843 that the Brahmo Somaj of Ram Mohan Roy was united with another _Sabha_ organized by another great soul, Debendra Nath Tagore. Under the guidance of this sturdy reformer, the Brahmo Somaj movement put on new life and energy. Debendra Nath was very devout and courageous. He was opposed to the religion of his fathers, as practised by the people. Nevertheless, he was somewhat anchored to the past. He still clung to the Hindu scriptures and regarded the Vedas as infallible. Later, however, as these Hindu writings were studied with more care, his faith in them was considerably shattered, and he began to deny their supreme authority. He and the other members of the society here entered upon a great struggle which ushered them into an "Age of Reason." The Vedas were abandoned as an ultimate authority, and the Brahmo Somaj, for a time, became "a Church without a Bible," and without any anchorage but the higher reason of its members. In 1852, the society was reorganized. Reason was soon found to be inadequate as the foundation of faith; and they passed on to an intuitional basis. That again seemed to be even more unsatisfactory than reason itself. After a few years, the movement gradually developed a doctrine of inspiration, when the utterances of the leaders themselves were regarded as inspired and became the voice of God to the members. Thus, within a few years, Brahmo Somaj moved almost in a circle, in its search for a stable anchorage to its faith; and it returned to a point dangerously near to the Hindu position which it had left a few years before. The rapid movement above indicated was chiefly owing to an ardent youth, who rallied to the support of Debendra Nath, and who gradually took the reins into his own hands. This young man was Keshub Chunder Sen; and he soon became the leading figure, certainly the most striking, in the whole theistic movement of India. He acquired growing influence over Debendra Nath, became the controlling spirit, and continued until his death to be the central figure of Theism in India. Chunder Sen was a great enthusiast, full of intellectual resource, and, withal, a man of deep spirituality. He was an Oriental of the Orientals; his mind was of a thoroughly mystic type, and, like the devout Hindu, he loved the rigours of asceticism, and, in not a few instances, yielded to the fascinations of the methods of the Yogi.
