Shamanic drumming awakens your ability to commune with your inner self and retrieve information. You need only journey within to find answers to any question. For a journey to the Lower World, visualize an opening into the earth that you remember from sometime in your life. The entrance could be an animal burrow, hollow tree stump, cave and so on. When the journey begins, you'll go down the hole and a tunnel will appear. The tunnel often appears ribbed and may spiral around. This tunnel-like imagery is related to the central axis that links the three inner planes of consciousness. Enter the tunnel and you will emerge into the Lower World, the realm of power animals, spirit guides and ancestral spirits. When you hear the sound of the callback, begin your return journey. Try to retrace the same route back; otherwise you might have trouble remembering the details of your journey.
