Right now you are a slave. You might think you are free, but you are a slave to your memories and programming, because they tell you what is good and what is bad, what is correct and what is incorrect. The intellect puts labels on everything, but there is no right or wrong. The mind thinks it knows, but it knows nothing.
We have become so entrenched in the belief that the intellect's purpose is storing and understanding information, that we base our sense of identity on this idea. Our intellect thus tries to become something that it is not and is always pushing us to be something that we are not meant to be.
Slowly, what others think of us becomes incredibly important, and we start looking for approval outside. We become masters at comparing ourselves to others and seek perfection according to external parameters beyond our control. Once we learn these lessons, we feel miserable most of the time.
Thoughts are extremely powerful, and unfortunately, most of the time they are tainted by our beliefs, emotions, and attachments. We do not think on a blank slate, free from preconceptions, biases, fears, and judgments. Everything we think of is based on our memories, our programming.
