又外道法，是倒說者，即邪聞法也。所有禁戒，非可現見等者，外道苦行持戒有因無果可現見故，是邪行法也。所有等至，有熱惱，非究竟等者，是邪證法也；翻此名正。

Furthermore, 'the teachings of non-Buddhists are inverted teachings' refers to the erroneously heard teaching. 'Whatever moral precepts [they hold] are not visible to direct perception,' etc.: because the austerities and keeping of precepts of non-Buddhists have a cause but no fruit that can be directly perceived, they are erroneous dharmas of practice. 'Whatever meditative attainments [they have] possess vexation and are not ultimate,' etc.: these are erroneous dharmas of realization. The reverse of these is called 'correct'.
