Original Japanese calligraphy by Yukari Haverstock. It's the Japanese translation of an excerpt from William Blake's "Auguries Of Innocence".
To see a World in a Grain of Sand
And a Heaven in a Wild Flower
Hold Infinity in the palm of your hand
And Eternity in an hour.
ひとつぶの砂に ひとつの世界を見
一輪の野の花に ひとつの天国を見
手のひらに無限を乗せ
ひと時のうちに永遠を感じる。
