When looking at the brain, it is important to go beyond its structure to its function. This is because often in cognitive disorders, the structure of the brain is intact, but its function is compromised.
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.
We admit, in geometry, not only infinite magnitudes, that is to say, magnitudes greater than any assignable magnitude, but infinite magnitudes infinitely greater, the one than the other. This astonishes our dimension of brains, which is only about six inches long, five broad, and six in depth, in the largest heads.
The more one listens to ordinary conversations the more apparent it becomes that the reasoning faculties of the brain take little part in the direction of the vocal organs.
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.
Narrow The heart that loves, the brain that contemplates, The life that wears, the spirit that creates One object, and one form, and builds thereby A sepulchre for its eternity.
Art bids us touch and taste and hear and see the world, and shrinks from what Blake calls mathematic form, from every abstract form, from all that is of the brain only.
There are three kinds of brains. The one understands things unassisted, the other understands things when shown by others, the third understands neither alone nor with the explanations of others.
