[Explanation]: ‘Is [a] Buddha named Āmítuó[fó’, is the] Preface’s Direct Reward’s master teacher’s name.
[Its] translation [is] as below, extensively explained.
[The] Buddha has Three Bodies, each [to be] discussed solely [and] in detail.
[The] Dharma Body solely, refers [to] those realised principles’ nature.
[The] Reward Body solely, refers [to those] able [to be] realised meritorious virtues [and] wisdom.
[The] Manifestation Body solely, refers [to] those appeared forms [with] excellences’ physical images.
That Dharma Body in detail, [is] Self-Nature’s pure Dharma Body, [with] departure [from] defilements’ extremely wonderful Dharma Body.
That Reward Body in detail, [is the] personally received [and] used Reward Body, [and] others’ received [and] used Reward Body.
That Manifestation Body in detail, [are] appearing [with] birth’s Manifestation Body, responding [with] appearances’ Manifestation Body, also Buddha realm’s Manifestation Body, [and] according [to] types [of sentient beings’ needed] Manifestation Body.
Although distinguished solely [and] in detail [as] Three Bodies, [they are] truly not one [and] not three, yet three, yet one.
Not vertical [or] horizontal, not together [or] separate, departed [from] faults [of the Four Lines and] surpassing [the Hundred] Nots, [they are] inconceivable.
[Note: The Four Lines (四句) are the  is line (有句),  emptiness line (空句),  also is also emptiness line (亦有亦空句), and  not is not emptiness line (非有非空句). The Hundred Nots (百非) are the Four Lines applied to each of the Four Lines, becoming (4 times 4) 16 lines, also with each of the 16 lines with the Three Times (三际) of past (过去), present (现在) and future (未来), becoming (16 times 3) 48 lines, also with the already arisen (已起) and yet to arise (未起), becoming (48 times 2) 96 lines, also adding the original four lines, to become the 100 lines of the Hundred Nots.]
Now, [who] called ‘Āmítuófó’, precisely refers [to the] Together Dwelling Land within, [his] appearing [with] birth’s Manifestation Body, [which] yet again, is the same as [the] Reward [Body, and] is the same as [the] Dharma Body.
