In Taoism, vitality (sexuality), energy (strength), and spirit (intelligence) are called "The Three Treasures." Thomas Cleary, who holds a doctorate in East Asian Languages and Civilizations from Harvard University, has translated five ancient Chinese Taoist texts uncovered in the Han Dynasty tombs between 1972 and 1974. In Talk on Supreme Guidance for the World, there is the comment: "Human beings are born able to do two things without learning how: one is breathing, the other is feeding. Everything other than these two things has to be learned and practiced."
Managing mind and energy is the key to mastering what the Taoists called "the bedroom arts." Two pieces focus on this subject: "Ten Questions" includes recommendations for men on satisfying women through prolonged intercourse and control of ejaculation while "Joining Yin and Yang" examines sexual techniques.
The same care and consideration that goes into making one a "celestial knight" is at the heart of being a good leader. In "A Course in Effectiveness" we read: "The greatest things in the world are done while still slight; so wise leaders never do big things, and thus can achieve greatness." The same treatise offers wise counsel on the path to living a long time: "If you know when you have enough, you won't be disgraced; and if you know when to stop, you won't be endangered."
