Mindfulness Of Buddha Is Unsurpassable Meditation
If [a] person [is] only mindful [of] Āmítuófó [by name or image, this] is named [as] unsurpassable profound [and] wonderful meditation. When [with the] sincere mind [reciting or] visualising seeing [the] Buddha, [this] is the same as [the] non-arising [and] non-ceasing Dharma.

[Note: When the true Buddha is aligned to and seen with practice, since the Buddha represents non-arising and non-ceasing truth, this is synonymous with the essence of the Dharma.]
