In "Travel Within: 7 Steps to Wisdom & Inner Peace," the book often refers to a plan of salvation. Unlike religious salvation, which looks outside ourselves and depends on an outside force to save us, Hosseini's plan of salvation requires us to become our own saviors. The book argues it is more necessary than ever to look inside ourselves and find inner peace to avoid impending cataclysmic disaster. The "disaster day" Hosseini refers to has been referenced by spiritual, religious and scientific philosophers. Instead of waiting for a big "disaster day" when something greater than ourselves will save us, the book urges people to find salvation within by achieving oneness here and now. The 7 Steps chronicled in the book allow readers to understand the path to achieving oneness and the wisdom of life.

Hosseini himself has lived life as both a Hindu and Buddhist, and came to the realization about an inner plan of salvation after a near-death experience.  The plan of salvation is not as easy to follow as blind faith in one religion or another, but it is much more empowering and gratifying. Perhaps so many struggle to find faith because the notion of looking outside themselves for salvation doesn't ring true on some level; a reason that makes picking up "Travel Within" such a compelling decision. "Travel Within" is one of the best books written on the topic of spiritual self-help, imparting a deep wisdom about life and spirituality while helping readers gain their own inner peace and happiness. It's an important book for believers and nonbelievers alike, and will help shed light on the human consciousness and what it means to "be."
