Alpha waves in the human brain are between 6 and 8 hertz. The wave frequency of the human cavity resonates between 6 and 8 hertz. All biological systems operate in the same frequency range. The human brain's alpha waves function in this range and the electrical resonance of the earth is between 6 and 8 hertz. Thus, our entire biological system - the brain and the earth itself - work on the same frequencies. If we can control that resonate system electronically, we can directly control the entire mental system of humankind.
In order to explain why the ordinary Sadhus and Yogis take to tobacco and gānja [an intoxicant], I said that these cause stimulation of the physical brain. But these have reactions. And to stimulate the brain thus is not the proper process.
Anything that is secret and mysterious in this system of Yoga should be at once rejected. The best guide in life is strength. In spirituality, as in all other matters, discard everything that weakens you. Have nothing to do with it. Mystery-mongering weakens the human brain. It has well-nigh destroyed Yoga, one of the grandest of sciences
Abnormalities in brain function have traditionally been detected using electroencephalography (EEG), which involves the measurement of the ongoing electrical activity generated by the brain.
I studied Hitchcock and Josef von Sternberg under Richard Dillard at Hollins, and that year under his tutelage just completely rewired my brain. Both directors combine moral seriousness with great artistry and, certainly in Hitchcock's case, an enormous respect for plot, for its power to enthrall and delight.
