vivāgasuyassa do suyakkhaṃdhā duhavivāgo suhavivāgo ya| tattha duhavivāge dasa ajjhayaṇā ekkasaragā dasasu ceva divasesu uddi-sijjaṃti| evaṃ suhavivāge vi| sesaṃ jahā āyārassa|

The Vivāgasuta has two śrutaskandhas: Duḥkhavipāka and Sukhvipāka. There, in Duḥkhavipāka, are ten adhyayanas of a single lesson each, recited over ten days. So too in Sukhvipāka. The rest is as in the Ācāra.
