頗胝（竹遲反梵言塞頗胝迦此云水玉或言白珠舊言頗黎是也大論云此寶出山石𰍅中過千年氷為頗黎珠案西域暑熱無氷極饒此物非氷所化但石之類）。

Phaṭika (竹遲 [zhú-chí] fanqie. Sanskrit says sphaṭika. This is translated as "water jade" or "white pearl." The older texts saying poli are this. The Mahāvibhāṣā states that this jewel comes from within mountain rocks and caves, where after a thousand years ice becomes poli pearls. Note: in the Western Regions it is hot and there is no ice, yet this item is extremely abundant; it is not transformed from ice, but is simply a kind of stone).
