Takeda Shingen quotes:

Knowledge is not power, it is only potential. Applying that knowledge is power. Understanding why and when to apply that knowledge is wisdom!

One who was born in the house of a warrior, regardless of his rank or class, first acquaints himself with a man of military feats and achievements in loyalty....Everyone knows that if a man doesn't hold filial piety toward his own parents he would also neglect his duties toward his lord. Such a neglect means a disloyalty toward humanity. Therefore such a man doesn't deserve to be called 'samurai'.

Arouse a bee and it will come at you with the force of a dragon.

Zen has no secrets other than seriously thinking about life and death.

A man with deep far-sightedness will survey both the beginning and the end of a situation and continually consider its every facet as important.

Learning is to a man as the leaves and branches are to a tree, and it can be said that he should simply not be without it.

Men with discrimination will be viewed as schemers; second, men with deep far-sightedness will be seen as cowards; and third, men with rough behaviour will be mistaken for real warriors. These are great errors.
