"Namboroku", a forged text, says that a poem created by FUJIWARA no Ietaka was included in "Shin Kokin Wakashu" (there is no poem like this in the collection though) and it describes well the essence of Rikyu's tea ceremony, which denied superficial decoration and pursued substantial beauty. The poem goes like this: to the people who consider only flowers beautiful, I would like to show the grass in the snow which brings the spring.
偽書である『南方録』では、新古今和歌集（実際は新古今和歌集には見当たらない）の藤原家隆の歌「花をのみ　まつらん人に　やまざとの　ゆきまの草の　春をみせばや」を利休の茶の心髄としており、表面的な華やかさを否定した質実な美として描かれている。
