德叉迦（此云能害於所害也謂德叉是所害聲迦是能害聲言此龍嗔時噓視人畜皆致命終也舊云多舌龍由多言故名多舌非是口中多舌也）。

Takṣaka (德叉迦: translates here as 'able to harm that which can be harmed'. 'Takṣa' is the noun for 'that which can be harmed', and 'ka' is the noun for 'able to harm'. It means that when this nāga becomes angry, exhaling his breath and glaring, humans and beasts alike all lose their lives. The older translation as 'Many-Tongued Nāga' [多舌龍] was because he talks much, hence called 'many-tongued', not that he actually has multiple tongues in his mouth).
