How it works
Before you start, make sure you are prepared for the journey, as explained in the related lessons. Understand what you need to do and pick the shamanic world to go to.
The drumming is by Michael Harner, the famous anthropologist. It keeps a steady pace all the time and speeds up at the end: that is your signal that the journey is almost done.
Never listen to it while driving.
Why it works
Looks like shamans knew about theta brain waves much earlier than they were discovered by scientific measurement! Theta waves have a frequency of 4–8 Hz, and that's exactly the frequency of shamanic drumming. Theta waves are used to reach the "mind awake, body asleep" state.
