Here is one of apparently 1.2 quadrillion hz. Human ears can pick up to 20,000hz but the Pineal Gland has no limit. Anyways I've had great success with binaural beats, you can use them to manifest a lot of things, I've been experimenting with them it just takes some time but I can't prove anything. Listening to positive affirmations is helpful too. Mind over matter but also matter over mind (diet).
