五失相應臥具者，指如聲聞地，多定樂中有六，修止舉捨入住出，多思擇中有四，謂勝善慧名思擇者，此出思擇體。

As for bedding and seats conjoined with the five faults, this refers to [the explanation] as in the Śrāvakabhūmi. In "much joy of concentration" there are six: cultivating calming, uplifting, equanimity, entering, abiding, and emerging. In "much discrimination" there are four: superior wholesome wisdom is called discrimination, which presents the essence of discrimination.
