妙法蓮華經玄贊 2.31

2.31

贊曰：下列名，為二：初列、後結。合有十八菩薩，皆以願行為名，分為七對。此中初三拔苦與樂對。

The commentary: Below, the names are listed, which comprises two parts: first, listing them; second, concluding. Altogether there are eighteen bodhisattvas, all named after their vows and practices, divided into seven pairs. Here, the first three form the pair of removing suffering and granting joy.
