Filmmaker Nick Polizzi, creator of the hit documentary The Sacred Science and highly popular website of the same name, takes readers on a spiritual adventure in the native outback of South, Central, and North America to access sacred knowledge the world has all but forgotten.

In the work of documentary filmmakers, explains Nick Polizzi, one cardinal rule is to establish the trust of your subject, but never forget that your job is to document, not participate. But when Nick set out to explore the native outback of the Americas-meeting healers, shamans, and medicine women and tapping their well of ancient wisdom, nearly lost to the rest of the world-he had to bend that rule. As he found his way into highly sacred and often very private shamanic ceremonies, not participating ceased to be an option.

In The Sacred Science, Nick invites readers along on his journey of discovery to make indigenous knowledge of healing accessible to us all.
