8.91

若人為佛故　建立諸形像
乃至童子戲　若草木及筆
或以指爪甲　而畫作佛像
如是諸人等　皆已成佛道

"If someone, for the Buddha’s sake, / sets up various images, / even down to children at play / who, with grass, sticks, or brushes, / or using their own fingernails, / draw images of the Buddha— / all such people as these / have already accomplished the Buddha Way."
