The goal and Purpose in Writing this book is to highlight, in the midst of diversity, the essential unity that seems to be constitutive of such Religions that have an orientation that is deeply mystical. Basing himself on the absolutistic Metaphysical thought of Kashmir Saivism, The Author thereby has attempted to interpret spirituality in such universal terms as would enable one to discover the principle of unity of being among the spiritualities of all major religions. Thus the aim of the book is so noble as to allow the reader to have the vision of unity in the midst of diversity.
