[i] Mindfulness [Of] Buddha Must [Be] Careful, [To] Not [Be] ‘Possessed’ [With] Compassion [And] Joy ‘Demons’
Of people learning Buddhism, [with each] one action [and every] one movement, all must [be] careful. As for mindfulness [of the] Buddha[‘s name (Āmítuófó), there] must [be] sincere wholeheartedness.
Perhaps, sometimes within [the] mind, [with] grief [and sorrow] arising, this also is [a] sign of good roots rising [and] appearing, [but one] must not enable it [to] frequently [be] thus. Otherwise, [one] will [be] ‘possessed’ [with the] compassion ‘demon’.
When having all agreeable [and] comfortable, [there] must not [be] excessive joy. Otherwise, [one] will [be] ‘possessed’ [with the] joy ‘demon’.
 [ii] Mindfulness [Of] Buddha Must [Be] Arbitrated, [When] Quietly Sitting Not Clutching Beads
When mindful [of the] Buddha[‘s name, the] eyelids must [be] drooping down. [There] must not [be] bracing [of] vitality [that is] too extreme, with [this] leading [to the] heart’s fire upward blazing, or having [the] top [of the] head itching, giving rise [to] pain [and] other illnesses. [There] must [be] arbitrating [and] moderating.
[If] aloud reciting, [there] must not [be] excessive exerting [of] strength, with [this for] preventing receiving [of] sickness.
[If] clutching beads reciting, [this is] able [to] prevent laziness.
When quietly sitting, [there] must not [be] clutching. [With] clutching, then [with] fingers moving, then [will the] mind not [be] able [to] concentrate. [After] long, [this] will receive sickness.
