With this track, you may want to try to concentrate on the low-frequency binaural wobbling in the lower end of the frequency spectrum, which slows down as you go along.
To summarize the important points:
- Completely relax your body.
- Relaxation of the body is necessary, but not sufficient. You must free your mind from any sort of thoughts.
- Concentrate on one thing, on which you can hold your concentration easily. If you catch yourself thinking about something else - simply get back on track.
- Stay aware.
