“When you spend significant amounts of time with someone they offer constant feedback, becoming part of the patterning of your brain. In other words, part of you. But I take your point -- constant feedback is not always deep feedback. A good measure of how much of you they've become is your level of distress when they're gone. If they form a large measure of your patterning, then you'll experience a major culling of the self. That's what's known as grief.”

“You are a self and an other.Your 'others' are in part your own creation.This in turn affects and shapes your experiences of self.Your levels of self-awareness and self-acceptance largely shape how you perceive others. p.231”

“Exercise has a direct brain connection, when you consider what it actually does. What we tend to overlook are the feedback loops that connect the brain to every cell in the body. Therefore when you throw a ball, run on a treadmill, or jog along the shore, billions of cells are "seeing" the outside world. The chemicals transmitted form the brain are acting the way sense organs do, making contact with the outside world and offering stimulation from that world.This is why the jump from being sedentary to doing a minimal amount of exercise - such as walking, light gardening, and climbing the stairs instead of taking the elevator - is so healthy. Your cells want to be part of the world.”

“In an extroverted society, we rarely see ourselves in the mirror. We get alienating feedback. Alienating feedback comes in the form of repeated encouragement to join or talk, puzzled expressions, well-intended concern, and sometimes, all-out pointing and laughing. Alienating feedback happens when we hear statements like, “What kind of loser would be home on a Saturday night?” Alienating feedback happens where neighborhoods, schools, and offices provide no place to retreat. Alienating feedback happens when our quiet spaces and wilderness sanctuaries are seen as places to colonize.”

“Computers are great because when you're working with them you get immediate results that let you know if your program works. It's feedback you don't get from many other things.”

“The combination of the Main brain with its central nervous system, and the ancient Animal Brain with its somatic, enteric nervous system in the inner body—in the gut—and the constant dialog between them provides a self-correcting feedback system, which regulates the behavioral qualities of the organism when consciously cultivated—preferably in early youth.”
