Methods of Entrainment In this session we will learn about brainwave entrainment, and the various types of sonic entrainment that are commonly used to shift states of consciousness. The brain, the heart and the breath are all connected. These tools of entrainment can help to relax our entire body and create a new level of harmony. Building on what we learned about cycles in the previous lessons we will learn how listening to sonic entrainment can help to encourage more relaxed states of consciousness.
