Hello all...
When you want to go into that path, beware not to fall into the force of darkness.
Meaning, in this world there is only 2 sources of supranatural powers, one from God, and the other from the Devil.
If you want supranatural powers, just pray and get closer to God. If you follow dont-know-what rituals and expect fast results, it is likely you are worshipping the Devil. As a result you will get ur supranatural powers quickly but u fall into the darkness and will be toyed with by the Devil.
Ok.....
My friend told me about his former employee, he could 'tap' using his fingers instead of an ouija board. End up in a serious possessed case and talked in a foreign language (It was a language from a country he never been to, but my friend knew).
So just be careful....
About that delta and theta...they simply mean states of mind. When you are deeply relaxed, you can remember better, think better, concentrate better, etc. That kind of idea. And if you train yourself, supposedly u can enter this phase as you wish.
I once saw a demonstration. It was a course teaching people about brain waves. A former graduate was called to the front to demonstrate to us. The speaker chatted with each of us. Asked about what we're thinking. Answers range from burgers to cars to soccer teams to pets. It was amazing, she could remember and recall everything we said, down to details and our names. Including my answer at that time. She could recall my pet, his coat colour, his name, his breed. And thats only from me. She did this for each and every one, close to 20s. One or 2 guys (see, even I can't remember) gave a phone number. You have to be there, it was way too amazing, she could recall even the numbers.
OK.....but dont use mythical/ supranatural powers. It's too dangerous IMO.
