Combining binaural beats with Mhz (Megahertz) and bpms (beats per minute) creates a rhythmic rhythm.
Depending upon your own natural rhythm of bpm’s will determine if a # of Mhz is relaxing in order to meditate.
If your own core of Mhz runs at high speed a slow bpm will create friction and mind chatter will ignore the bpm’s, as if they do not exist.
If you own core of Mhz runs at low speed a slow bpm will create harmony, and you are out like a baby fast asleep.
To know your own bpm’s is with testing.
