He who embodies the fullness of integrity is like a ruddy infant. Wasps, spiders, scorpions, and snakes will not sting or bite him; Rapacious birds and fierce beasts will not seize him. His bones are weak and his sinews soft, yet his grip is tight. He knows not the joining of male and female, yet his penis is aroused. His essence has reached a peak. He screams the whole day without becoming hoarse; His harmony has reached perfection. Harmony implies constancy; Constancy requires insight. Striving to increase one’s life is ominous; To control the vital breath with one’s mind entails force. Something that grows old while still in its prime is said to be not in accord with the Way; Not being in accord with the Way leads to an early demise.
