The very last poem made just thirteen days before his passing:
The poem made on the evening of the 15th of August in the
year (1253 C.E.) of his entering nirvana (August 28):
Even in the autumn, when
I’d expect seeing again,
I could not have slept
With the moon of tonight.
Gonyūmetsu-no toshi hachi-gatsu jūgoya gyo-eika-ni iu
Mata minto
Omoishi tokino
Aki-danimo
Koyoi-no tsuki-ni
Nerareyawasuru
御入滅之年八月十五夜、御詠歌に云
又見んと
思ひし時の
秋だにも
今夜の月に
ねられやはする
Note: The full moon represents the Buddha heart,
perfectly round, harmonious, fully clear and calm.
