In the early modern period since the seventeenth century, after contact between East and West became vigorous, Indian religious thought was introduced to the West and attracted the attention of Western intellectuals. One of these intellectuals was the Lutheran theologian Rudolf Otto (1869–1937). In his works on Indian religious thought, Otto focused on Vedanta philosophy, represented by Sankara and Ramanuja, and on Vaisnava faith in Hindu religious tradition. According to his framework of religions, the Hindu tradition as the “bhakti religion” corresponds to the Christian tradition in the West. From a comparative viewpoint of religions, based on his Christian theological studies, he argued that religions provided “parallel lines of development” in the East and the West. In my lecture, I would like to clarify the characteristics of Otto’s perspective of Indian religious thought from a hermeneutical perspective of religion and to re-examine to what extent his view may be adequate for the understanding of Hindu tradition.
