Humans have yet to dwell upon ...

Humans have yet to dwell upon the consequences of their
 actions. People have yet to admit the bad that they do to
 nature, for example. Actually, most people spend their time
 finding fault in the action of others, rather than their own.

Always be able to kill your students
 Masaaki Hatsumi
What I want you to do is just take it as it is. Don't think too much. If you get involved with thinking about it, the whole thing gets lost or loses its purity. Don't think during practice - DO! The more you think, the further from the truth of budo you get: Budo is NOT an academic subject!
 Masaaki Hatsumi
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.
