Rhythm is in your heartbeat. It pulses through your respiration and internal muscular flows. Your nerves fire in patterns of rhythms. Rhythms are essential to every part of life. They're the mathematical and geometrical patterns of nature.
Hypnotists use rhythm to induce trance.
Rhythm can take you into areas your consciozus mind can't just will itself into. Rhythm is a password. It can guide you through gateways of perception. Rhythm is about time. It happens when the timing of different and perhaps otherwise unrelated events can be described by a formula, or a code.
