OK, let me clarify this: That can be measured. Show me something else out there that can be demonstrated or measured in some way that can go deeper. To my knowledge nothing can because it drops off the perception range.

I have heard of lower levels of brain waves but so far no one has been able to clearly demonstrate them and it is probably operator error that was really behind it.

Yes there is the yogi whom can stop his heartbeat but did he stop his brainwave?

Would you agree that deep meditation is related and measureable by brain wave activity or is there another system you choose?
