This is a simple exploration down through the tunnel into the Lowerworld. The only mission is to travel the tunnel and perhaps see what lies beyond. Make sure you thoroughly understand the instructions before beginning the journey.

To carry out the exercise, you will need a second person to act as a drummer, or a cassette recording of Shamanistic drumming.

Wait until you are calm and relaxed before undertaking any Shamanistic journey. Avoid alcohol or any psychedelic substances for at least four hours before the exercise. Eat only lightly, or not at all during the preceding four hours.

Choose a dark and quite room. Loosen or remove your clothing and lie comfortably on the floor without a pillow. Take a few deep breaths and relax your arms and legs. Lie there and contemplate your forth coming mission. Then close your eyes, placing a hand or forearm over them to keep out any light.

Now visualize an opening into the earth that you remember from sometime in your life. It can be one you remember from childhood, or one you saw yesterday. Any kind of entry into the ground will do. It may be a hole made by a burrowed animal, a hollow tree stump, a spring or even a swamp. It can even be man-made. The right opening is one that feels comfortable to you, and one which you can visualize. Spend a couple of minutes seeing the hole, without going into it. Note it's details clearly.

Now either start the cassette recording, or instruct your companion to begin drumming. The drumming should be a strong, monotonous, unvarying, rapid beat. There should be no contrast in the intensity of the drum beats, or the intervals between them. A drumming tempo of about 205 to 220 beats per minute is usually effective for this kind of journey. Allow yourself ten minutes for the journey. At the end of that time, the drummer should indicate that your time is up by striking four sharp beats to signal that it is time for your return. The drummer should then beat the drum very rapidly for about half a minute to accompany you on the return journey, concluding with four more sharp beats to signal the end of the journey.

When the drumming begins, enter your opening into the earth. Go down through the opening and enter the tunnel. At first the tunnel might be dark and dim. It might go underground at a slight angle, or it might descend steeply. Sometimes the tunnel appears ribbed, and often it bends. Occasionally one passes through the tunnel so fast that it is not even seen. In following the tunnel, you may run right up against a natural wall of stone, or some other obstacle. If this happens, just go around it, or through a crack in it. If this fails, simply come back and try again.

At the end of the tunnel, you will emerge out of doors. Examine the landscape in detail. Travel through it and remember it's features. Explore until you are signaled to come back, and then return through the tunnel the same way you went down.

DO NOT BRING ANYTHING BACK WITH YOU.
