觀無量壽佛經疏 4.69

4.69

七、從當華敷時下，至八解脫已來，正明第十一門中華開已後得益不同。即有其三。一明寶華尋發，此由戒行精強故也。二明法音同讚四諦之德。三明到彼聞說四諦，即獲羅漢之果。言羅漢者此云無生，亦云無著，因亡故無生，果喪故無著。言三明者，宿命明，天眼明，漏盡明也。言八解脫者。內有色外觀色，一解脫。內無色外觀色，二解脫。不淨相，三解脫。四空及滅盡，總成八也。

Seventh, from "when the flower blossoms" down to "eight liberations," it directly clarifies, under the eleventh gateway, the differences in benefits gained after the flower opens. This consists of three points: First, it clarifies that the jeweled flower opens immediately, which is due to the vigor of their observance of the precepts. Second, it clarifies that the sounds of the Dharma together praise the virtue of the Four Noble Truths. Third, it clarifies that upon arriving there and hearing the Four Noble Truths expounded, they immediately attain the fruit of an arhat. "Arhat" is translated here as "unborn," and also as "unattached": because causes are extinguished, they are unborn; because fruits are discarded, they are unattached. The "three clarities" are the knowledge of past lives, the divine eye, and the extinction of outflows. The "eight liberations" are: possessing inner form and contemplating external form is the first liberation; lacking inner form and contemplating external form is the second liberation; contemplating the mark of impurity is the third liberation; together with the four formless attainments and cessation, these constitute eight in total.
