Theta/ Gamma sinc

Dear Evocationist: Greetings!

I am having a hard time to understand this videos in English, I am Spanish, I ordained from Amazon " Evoking Eternity" Is there an explanation about Theta/ Gamma sinc.?

Could you explain me brevely this Magical technic please?.
What is the right time in evocation magic to use this technic?



Just listen to 4.5hz binaural beats, while in the lotus position, and focus on your breathing. This will get you into the required trance state. The state must be held for the whole duration of the ritual.

Thanks Elison!
