A small book carrying an immense truth: that all the world's religions point to the one same goal.

• The Science of Religion had its origin as Gurudev Yoganandaji's maiden address in America — a speech later amplified by him into this compact but profound volume. Within it lies the seed of his life's teaching: that religion, rightly understood, is not a matter of blind faith but a precise, verifiable science of the soul.
• Yoganandaji's central revelation is offered in a single, luminous sentence: "The sense of identification with the transitory body and restless mind is the source or root-cause of our spiritual Self's misery." In this one line lies the diagnosis of all human suffering — that we have forgotten our true nature and mistaken the perishable vehicle of body and mind for the imperishable Self within.
• The book stands as a testament to Gurudev's unique gift — the ability to distill the loftiest truths of the Vedas and Upanishads, and the practical science of Patanjali's yoga, into language a modern seeker can grasp and apply. It is, quite literally, described as holding "the flower of the Vedas and Upanishads, the essence of Patanjali" within its narrow covers.
• Its brevity is deceptive and its purpose devotional as much as intellectual. Every page invites not mere reading but reflection, sadhana, and inner verification — in keeping with Gurudev's constant emphasis that spiritual truth must be realized directly, not simply believed.
• For disciples and sincere seekers alike, this small volume is rightly called "the clue to the universe" — a fitting gateway into Gurudev's larger teachings, and a worthy companion to his Autobiography of a Yogi.
• The Science of Religion is available in ten languages — English, Hindi, Bengali, Gujarati, Kannada, Malayalam, Telugu, Marathi, Odia, and Tamil — at shop.ideazfirst.com.

With reverence and gratitude to Gurudev Sri Sri Paramahansa Yoganandaji, whose words continue to illumine the path of countless seekers.
