瑠璃為幹（哥旱反瑠璃梵語具云吠瑠耶此名不遠山謂西域有山去波羅奈城不遠此寶出彼故以名之幹者字書云幹枝也謂麤也字冝從于經本有從木者謬也案孔安國注書杜注左傳及勘玉篇皆以從干為樹麤枝從木為築牆板謂即兩當頭者謂之楨兩房者謂之幹也）。

Having lapis lazuli as its trunk (幹 is pronounced 哥旱. *Liuli* in Sanskrit is fully *vaiḍūrya*, which translates as 'not-distant mountain'. It refers to a mountain in the Western Regions not far from the city of Vārāṇasī; because this jewel is produced there, it was named after it. As for *gan*, character dictionaries say: "*Gan* means trunk/thick branch," referring to its stoutness. The character should properly be written with 干; versions of the sūtra written with the wood radical [木] are erroneous. According to Kong Anguo's commentary on the *Classic of Documents*, Du [Yu]'s commentary on the *Zuo tradition*, and an examination of the *Yupian*, the character with 干 refers to a thick tree branch, while that with 木 refers to planks used for building earthen walls—the planks at both ends are called *zhen*, and those along the two walls are called *gan*).
