Question: [If those with the] Five Transgressions can [still be] reborn [in Āmítuófó’s Pure Land], why [is the] Buddha not able [to] eradicate definite [or ‘fixed’ negative] karma?
[Note 1: The Five Transgressions (五逆罪) of killing father (杀父), killing mother (杀母), killing Arhat (杀阿罗汉), causing Buddha to bleed (出佛身血) and causing schism in Saṃgha (破和合僧) should create definite negative karma that is so heavy that it leads to rebirth in the lowest hell quickly by default. However, with sincere (and repentant) mindfulness of Āmítuófó, his great blessings connected to can dilute even the worst negative karma, thus avoiding fall into hell, even enabling reach of his Pure Land. As there is mindfulness of Buddha (念佛) with Faith (信) and Aspiration (愿) needed with some Self-power (自力) to connect to the Buddha’s Other-power (他力), he cannot eradicate one’s negative karma with his power alone.]
Also, persons [with heavy negative] karma, if using this [for] personal lenience, how [can they] not enter hell [swiftly] like arrows shot?
[Note 2: Those who already understand the teachings in Note 1 should not purposely create such negative karma. Thus, they are unlikely to use them for ‘letting themselves off the hook’. This is while it is usually those who do not understand them, who do create such negative karma.]
Answer: [A] thousand years’ darkened room, [with] one lamp[‘s brightness, is] able [to be] destroyed. [With] repentance’s power since earnest, [negative] karma [is] then without [that] definite.
[Note 3: Even if there is much negative karma accumulated over a long time, with Āmítuófó’s great light of blessings connected to, even if only for a short time, such karma will be eradicated. It is with true repentance (真心忏悔) that there will be earnest (i.e. sincere) mindfulness of Buddha, thus having this effect.]
If stubborn, foolish [and] confused, attaining [a] ship [but] not boarding [it, instead] pulling [on a] garment as [a] raft, [or] embracing [a] boulder as [a] boat, since without [the] power of turning around, [this] is truly definite karma [that is] difficult [to] escape [from]!
[Note 4: Having encountered these teachings of mindfulness of Buddha when otherwise bound to fall into hell, is to have attained a ‘rescue ship’ in time to reach Pure Land, while seeking other lesser refuge is to sink, karmically and accordingly. Thus, whether there is truly definite karma bearing fruit or not will depend on whether there is mindfulness of Buddha in time or not.]
