Do not harbor sinister designs.
Diligently pursue the path of "the two swords as one."
Cultivate a wide range of interests in the arts.
Be knowledgeable in a variety of occupations.
Be discrete regarding one's commercial dealings.
Nurture the ability to see the truth in all matters.
Perceive that which cannot be seen with the eye.
Do not be negligent, even in trifling matters.
Do not engage in useless activity.
- Miyamoto Musashi
