難頭和難頭（梵語二龍王名虜質不妙也正梵音云難努難字上聲是兄名也鉢難努難字上聲是弟名也即是諸經中難陀跋難陀兄弟二龍王也）。

難頭和難頭 Sanskrit words, the names of two nāga kings, here crudely and inelegantly rendered. The correct Sanskrit pronunciation is Nanda (with nán in the rising tone), which is the name of the elder brother; and Upananda (with nán in the rising tone), which is the name of the younger brother. These are the two brother nāga kings Nanda and Upananda mentioned across the sūtras.
