The truth of the theoretical speculations of Bankim was demonstrated by Ramakrishna Paramahansa, the greatest saint of the 19th century. Both by precept and example of his own life Ramakrishna brought home to an incredulous world, held under the spell of natural science, the reality of spiritual life and of the means to attain it as described in ancient Hindu scriptures, both Vedic and post-Vedic. He held that not only all the different forms of Hindu religion, including the Puranic and Tantric, but all religions, such as Islam and Christianity, are true in their essence and may lead to salvation, if properly pursued. This he demonstrated by himself practising with success the diverse modes of sadhana or spiritual discipline prescribed in the different religious cults mentioned above. ...Ramakrishna proved in his own life that the worship of Puranic deities through their images was as good a means of salvation as the worship of one God without any form. He gave a moral sanction, a philosophical basis and a new spiritual significance to the neo-Hinduism which laid the foundation of Hindu nationalism on a secure foundation.52
