The advantages of pursuing the path of Gnana Yoga, of an enquiry into Self, are manifold. It starts from the standpoint to which we are accustomed, by taking self as we find it. It does not start from some divine Brahman whose existence is initially known to but one man in millions (since it is to be apprehended only in Samadhi). The enquiry into Self, moreover, accepts this world as real, and does not ask us to go against every attribute of common sense. It permits our minds to work along their natural lines of thinking. It follows the method most suitable to our Western scientific minds--that is, it works from the known to the unknown.
