"Long ago, abdominal pains were called "cowardice grass." This is because they come suddenly and render a person immobile." - Yamamoto Tsunetomo

It is bad to carry even a good thing too far. Even concerning things such as Buddhism, Buddhist sermons, and moral lessons, talking too much will bring harm.

All that matters is having single-minded purpose ( ichinen), in the here and now. Life is an ongoing succession of ‘one will’ at a time, each and every moment. A man who realizes this truth need not hurry to do, or seek, anything else anymore. Just live in the present with single-minded purpose. People forget this important truth, and keep seeking other things to accomplish.

Nothing is impossible in this world. Firm determination, it is said, can move heaven and earth. Things appear far beyond one's power, because one cannot set his heart on any arduous project due to want of strong will.
