The human consciousness is a vast and powerful tool that we can sharpen and use to our benefit. If done correctly, this can create the foundation for achieving inner peace and happiness. The foundation of inner peace relies heavily on spirituality, but not a spiritual religion in particular. Instead of waiting for religion to save us, "Travel Within" argues that we are the only ones who can save ourselves and create a plan of salvation. Though written through the lens of Hosseini's personal life experience, "Travel Within" serves as a profound spiritual self-help book for individuals seeking inner peace and happiness. In a world where many things around us are falling apart - the economy, the nuclear family forms, ethics, and peaceful existence - "Travel Within" gives readers a way to look within ourselves and achieve a powerful peace and happiness.
