唯人はなさけあれ。夢の夢の夢の。昨日はけふのいにしへ。けふは明日のむかし。
[Tada hito wa nasake are. Yume no yume no yume no. Kinō wa kyō no inishie. Kyō wa asu no mukashi.]
People should simply have compassion. (Because this world is) like a dream, like a dream, like a dream. Yesterday is a bygone for today. Today is a past for tomorrow.
From 閑吟集[Kangin-shū], Collection of ballads compiled in the Muromachi period (1336 or 1392-1573)
