"Forget your sadness, anger, grudges, and hatred. Let them pass like smoke caught in the breeze. You should not deviate from the path of righteousness; you should lead a life worthy of a man. Don't be possessed by greed, luxury, or your ego. You should accept sorrows, sadness and hatred as they are, and consider them a chance for trial given to you by the powers... a blessing given by nature. Have both your mind and your time fully engaged in bud?, and have your mind deeply set on bujutsu."
