Rumination is the practice of lowering ones brain frequency from a waking Beta state to a slower Alpha state. Just as a heart beats a particular number of beats per minute, the brain pulses a particular amount of brainwaves per second. In the Beta waking state, brainwaves vary from 15 to 40 cycles per second. In the Alpha state, brainwaves vary from 9 to 14 cycles per second.
