Even if you hope to live for seventy or eighty years, in the end you are destined to die. You should regard your pleasures and sorrows, relationships… - Dōgen

At the time Dōgen Zenji was writing the Tenzo Kyōkun, he had already left Kennin-ji in Kyoto, and had set up his own monastery at Kōshō-ji in Fukakusa, just south of the city.
