In this book Seyyed Hossein Nasr explores a “sacred science” grounded in metaphysical first principles. Nasr argues that this science liberates the soul from modern materialism and secularism by restoring our connection to the sacred. He sees today’s deepest spiritual malaise as the result of that rupture—and insists that only by reclaiming traditional wisdom can we harmonize soul, society, and nature under the light of the Absolute.
