Nichinichi kore kōnichi

Nichinichi kore kōnichi (Japanese: 日々是好日) (Chinese: 日日是好日) is a Zen Buddhist proverb.

It is thought to be Yunmen Wenyan's answer in the sixth case of the kōan collection Blue Cliff Record.

[1][2][3][4] It has been presented by some Zen masters (notably, Kōdō Sawaki and his disciple Taisen Deshimaru).

[5] It was a favorite saying of the avant-garde composer John Cage, featured in Song Books (1970) as "Solo for Voice 64".

[6][7][8] As a Zen word in Japanese, the correct way to read the phrase is Nichinichi kore kōnichi.
