According to their nature, there are both people who have quick intelligence, and those who must withdraw and take time to think things over. Looking into this thoroughly, if one thinks selflessly and adheres to the four vows of the Nabeshima samurai, surprising wisdom will occur regardless of the high or low points of one's nature.' People think that they can clear up profound matters if they consider them deeply, but they exercise perverse thoughts and come to no good because they do their reflecting with only self-interest at the center.

It is difficult for a fool's habits to change to selflessness. In confronting a matter, however, if at first you leave it alone, fix the four vows in your heart, exclude self-interest, and make an effort, you will not go far from your mark.

Because we do most things relying only on our own sagacity we become self-interested, turn our backs on reason, and things do not turn out well. As seen by other people this is sordid, weak, narrow and inefficient. When one is not capable of true intelligence, it is good to consult with someone of good sense. An advisor will fulfill the Way when he makes a decision by selfless and frank intelligence because he is not personally involved. This way of doing things will certainly be seen by others as being strongly rooted. It is, for example, like a large tree with many roots. One man's intelligence is like a tree that has been simply stuck in the ground.

We learn about the sayings and deeds of the men of old in order to entrust ourselves to their wisdom and prevent selfishness. When we throw off our own bias, follow the sayings of the ancients, and confer with other people, matters should go well and without mishap. Lord Katsushige borrowed from the wisdom of Lord Naoshige. This is mentioned in the Ohanashikikigaki. We should be grateful for his concern.
