Every individual psychological system of ceaseless change is sustained by a central principle, which is constant, self-luminous, ever pure and free. The central principle of the microcosm is not different from the central principle of the macrocosm, that is to say, there is kinship or unity between the soul of man and soul of the Universe. The truth is, what is innermost in the one is innermost in the other. To realise this kinship or Unity is the Goal of life. So we find unity between man and men, man and God and between various religions.
Spiritual unity is the only common ground where men can meet in spite of their differences.
Unity in variety or plurality is the pattern for world culture. There is no conflict between one aspect of life and another. The Goal of Civilisation cannot be different from the Goal of Religion. The unification of the world with recognition of the spiritual oneness of mankind is the greatest aim of religion. Though the diversity of religion will remain, the different religions will co-exist as diverse paths of worship of the one infinite.
