"Believe nothing merely because you have been told it. Do not believe what your teacher tells you merely out of respect for the teacher. But whatsoever, after due examination and analysis, you find to be kind, conducive to the good, the benefit, the welfare of all beings -- that doctrine believe and cling to, and take it as your guide."
"There is a vitality, a life force, a quickening that is translated through you into action, and there is only one of you in all time, this expression is unique, and if you block it, it will never exist through any other medium; and be lost. The world will not have it. It is not your business to determine how good it is, not how it compares with other expression. It is your business to keep it yours clearly and directly, to keep the channel open. You do not even have to believe in yourself or your work. You have to keep open and aware directly to the urges that motivate you. Keep the channel open. No artist is pleased. There is no satisfaction whatever at any time. There is on a queer, divine dissatisfaction, a blessed unrest that keeps us marching and makes us more alive than the others."
