Tao Te Ching

“Of a man's abilities first comes knowledge of the teachings of the sages... Next should be learned the art of medicine. Without medicine, a man cannot care for his own body, nor help others, nor perform his duties to his parents”

— Yoshida Kenkō 兼好 1284 – 1350 CE via Sir George Bailey Sansom
