Chapter 1: are you really your body?
You are your body, right? You are chemical in essence ... right? At least, that’s what one of America’s most influential scientists claims:
I am a collection of water, calcium and organic molecules called Carl Sagan. You are a collection of almost identical molecules with a different collective label.*
Like Sagan, most people believe that they are their body. So if you ask them who they are, they think and respond in terms of bodily labels.
“I’m Susan. I’m blond, 29 years old, a mother, and still 36-24-36!”
“I’m Henry. I’m a white American male and proud of it!”
“I’m John. I’m a lawyer. I’m 40 years old and getting older every day.”
“I’m Alice. I’m a female student. I’m fat and I’m a Methodist.”
Name, race, age, sex, religion, nationality, occupation, height, weight, and so on—all these are bodily labels. Therefore if you consider your body to be yourself, you automatically identity yourself with such labels. If your body is fat and ugly, you think, “Woe is me! I am fat and ugly.” If your body is 60 years old and female, you think “I am a 60-year-old female.” If your body is black and beautiful, you think, “I am black and beautiful.”
But is the body really the self? Are you really your body?
Let me ask you a few simple questions: Do you exist at this moment? Did you exist five years ago? Are you your body? Most people would answer “yes” to all three questions. But if you identify your body as yourself, and simultaneously accept that you exist now and also existed five years ago, then you have a problem: The body you had five years ago does not exist today. There is a dynamic turnover of atoms and molecules which make up your body. There isn’t a single particle of matter—not one atom—present in your body today that was present five years ago. The body you have today is not the same body you had five years ago. It’s not that the body you had still exists but has now changed somewhat. No. The body you had is gone. That collection of atoms appearing as flesh, bone, blood, hair, and so on no longer exists. Yet you still exist.
Recent studies at the Oak Ridge Atomic Research Center have revealed that about 98 percent of all the atoms in a human body are replaced every year. You get a new suit of skin every month and a new liver every six weeks. The lining of your stomach lasts only five days before it’s replaced. Even your bones are not the solid, stable, concrete-like things you might have thought them to be: They are undergoing constant change. The bones you have today are different from the bones you had a year ago. Experts in this area of research have concluded that there is a complete, 100 percent turnover of atoms in the body at least every five years. In other words, not one single atom present in your body today was there five years ago.*
Nor is sense gratification considered “bad.” Sense gratification comes and goes as a natural occurrence of the senses. For example, one cannot eat without tasting. The point is that a life that is centered around sense enjoyment, that makes sense enjoyment the goal, is a wasted life. Economic development is necessary for the maintenance of the body; so therefore it cannot be neglected. But to seek economic development simply for the sake of endlessly increasing sensual pleasure is foolish. No amount of sensual pleasure will ever really satisfy a person, so no amount of economic development will ever be considered “enough.” This is why people in modern Western societies are still not satisfied, even though they are so economically advanced and thus have so much facility for sense enjoyment. They always want more.
Many people believe that a person is the brain or some part of the brain. You may be one of them. If so, the following should boggle your mind:
Recent studies on the turnover of the molecular population within a given nerve cell have indicated that ... their macromolecular contingent is renewed about ten thousand times in a lifetime.*
In other words, the matter making up each brain cell is completely renewed every three days.
Your brain—that mass of matter which is contained in your skull today—is not the same brain that was in your skull last week.
