Keeping Tau

"In governing men and in serving Heaven, there is nothing like moderation. This moderation, I say, is the first thing to be attained. When this is first attained, one may be said to have laid in an abundant store of virtue. With an abundant store of virtue, one may conquer every obstacle. Being able to conquer every obstacle, no limit can be seen to one's resources. And when this is the case, one may have the kingdom. Such an one has the Mother of the kingdom, and may endure long. This I call having the roots deep and the fibres firm. This is the Tau by which one may live long and see many days."
