菩薩戒本疏 2.149

2.149

若佛子！常應一心受持讀誦大乘經律，剝皮為紙，刺血為墨，以髓為水，折骨為筆，書寫佛戒。木皮、穀紙、絹素、竹帛，亦悉書持。常以七寶、無價香華、一切雜寶為箱囊，盛經律卷。若不如法供養者，犯輕垢罪。

"O disciples of the Buddha! You should constantly with single mind uphold, read, and recite Mahāyāna sūtras and vinaya texts; flay your skin for paper, pierce your blood for ink, use your marrow for water, and snap your bones for pens to copy the Buddha's precepts. Tree bark, mulberry paper, silk, and bamboo slips should all likewise be written upon and upheld. Constantly use the seven treasures, priceless incense and flowers, and all kinds of gems as boxes and bags to hold the scrolls of sūtras and vinaya. If one does not make offerings according to the Dharma, one commits a duṣkṛta offense."
