In his final course of Gifford Lectures, delivered at the University of Glasgow in 1892, F. Max Müller concentrates on the essential unity or oneness of the objective Infinite in nature (God) and the subjective Infinite in man (soul), which is the final consummation of all religious and philosophical endeavours. Much time is spent discussing the relation of the soul to Brahman in the Hindu philosophy of Vedanta, and of similar strains in the Sufi branch of Islam.

F. Max Müller’s second round of Gifford Lectures, delivered before the University of Glasgow in the beginning of 1890, builds on the introductory material laid out in his first course, Natural Religion, now taking as his focus Physical Religion. Müller defines physical religion as a worship of the powers of nature.
