"Styles tend to not only separate men - because they have their own doctrines and then the doctrine became the gospel truth that you cannot change. But if you do not have a style, if you just say: Well, here I am as a human being, how can I express myself totally and completely? Now, that way you won't create a style, because style is a crystallization . That way, it's a process of continuing growth."

It's important to make an effort under any circumstance - stagnant, sickness, being in an unstable lifestyle, even when society is insane. You should consider such periods as an omen before you move. When you are stuck on something, it is important to hold to your purpose but not press onward against the current. When you can't move at all, try to concentrate, continuing forward as if in a boat switching to a stronger motor. The keiko that is most important when you cannot move is kage no keiko [shadow training].
