excellent 'book', Hagakure the samurai handbook
From the very first page,
"Although it stands to reason that a samurai should be mindful of the Way of the Samurai, it would seem that we are all negligent. Consequently, if someone were to ask, "What is the true meaning of the Way of the Samurai?" the person who would be able to answer promptly is rare. This is because it has not been established in one's mind beforehand. From this, one's unmindfulness of the Way can be known.
Negligence is an extreme thing."
