第十八解學無學二種差別，是等字中第三門也。言五相者，則三無上為三，觀佛法身為第四，奉事如來為第五也。

The eighteenth part explains the two kinds of distinctions between learners and non-learners, which is the third heading under the word 'etc.' Regarding the 'five characteristics': the three unexcelled states constitute three, contemplating the Buddha's dharmakāya is the fourth, and attending upon the Tathāgata is the fifth.
