Ramakrishna was a Bengali mystic who had a huge impact on the development of modern Hinduism. His chief disciple, Swami Vivekananda, not only helped revive Hinduism in India, but also introduced Hinduism to the West. Ramakrishna was a non-dualist worshippper of the Goddess Kali. However, he also experimented with Christianity and Islam, and repeatedly preached the diversity of paths to God. This is the story of Ramakrishna told first-hand as a series of days and nights spent with his disciples and lay followers. --Sacred Texts
