Your body is just accumulation of the food, that you have gathered over period of time. One day you were a child, now you are a young or old man, the moment you were born to till you die, every moment the body is changing. Its constantly changing all the time from childhood.
Your mind is bundle of memories and thoughts, It is just information fed from everywhere, you see, you hear, you taste, you go on collecting the all kind of information through your senses, all become part of your memory and become mind.
You are not your body
You are not mind either
Don’t get identified with body or mind
You are more than your body and mind Know yourself, Who you are.
