"If a doctor, lawyer, or dentist had 40 people in his office at one time, all of whom had different needs, and some of whom didn't want to be there and were causing trouble, and the doctor, lawyer, or dentist, without assistance, had to treat them all with professional excellence for nine months, then he might have some conception of the classroom teacher's job."
Do not believe in anything simply because you have heard it. Do not believe in anything simply because it is spoken and rumored by many. Do not believe in anything simply because it is found written in your religious books. Do not believe in anything merely on the authority of your teachers and elders. Do not believe in traditions because they have been handed down for many generations. But after observation and analysis, when you find that anything agrees with reason and is conducive to the good and benefit of one and all, then accept it and live up to it.

They tell me I cannot change what is, I can only hope to change what will become. Let the grasses grow over our scars, they say, and let flowers bloom over our wounds.

What if you're practicing wrong? Then you get very good at doing something wrong. If we don't get good instruction, then we don't notice when it's a little out of round. Surrender yourself to your teacher. That's doesn't mean you turn over your life to the teacher - you don't want a guru. You have to keep the autonomy within yourself. You are finally the ultimate authority on your own practice.
