Singlemindedness is all-powerful. - Yamamoto Tsunetomo

Moreover, the child of parents who have a bad relationship will be unfilial. This is natural. Even the birds and beasts are affected by what they are used to seeing and hearing from the time they are born. Also, the relationship between father and child may deteriorate because of a mother’s foolishness. A mother loves her child above all things, and will be partial to the child that is corrected by his father. If she becomes the child’s ally, there will be discord between father and son. Because of the shallowness of her mind, a woman sees the child as her support in old age.

To say that dying without reaching one’s aim is to die a dog’s death is the frivolous way of sophisticates.

To hate injustice and stand on righteousness is a difficult thing. Furthermore, to think that being righteous is the best one can do and to do one's utmost to be righteous will, on the contrary, bring many mistakes. The Way is in a higher place than righteousness. This is very difficult to discover, but it is the highest wisdom. When seen from this standpoint, things like righteousness are rather shallow. If one does not understand this on his own, it cannot be known. There is a method of getting to this Way, however, even if one cannot discover it by himself. This is found in consultation with others. Even a person who has not attained this Way sees others from the side. It is like the saying from the game of go: "He who sees from the side has eight eyes." The saying, "Thought by thought we see our own mistakes," also means that the highest Way is in discussion with others.
