Thought is matter. There is energy and there is matter. That is all life is: energy and matter. We think thought is not matter, but it is. Thought is matter, as an idea, as an ideology. Energy becomes matter, so matter and energy are interrelated; one cannot exist without the other. Matter cannot exist without energy and energy cannot exist without matter; the two are completely interrelated. The more there is balance, harmony between energy and matter, the more the brain cells are active – not as an idea but actually active; much more.
