Your brain is an organ that thinks. The heart beats and circulates blood. The kidneys purify the blood and remove waste from the body. Toenails protect the toes.

If you don’t take care of your body it will become unhealthy.

If you don’t add structure to your brain to make it healthy, it will just keep thinking and thinking regardless if the thoughts are worthless or positive. That is what the brain is supposed to do, think thoughts all the time. Not all thoughts are good.
Children are not born divine. All living creatures have unique features.

When the great Tao is forgotten,
Kindness and morality arise.
When wisdom and intelligence are born,
The great pretense begins.

When there is no peace within the family,
Filial piety and devotion arise.
When the country is confused and in chaos.
Loyal ministers appear.
