evil persons are the right object of Amida's salvation
A Pure Land Buddhist concept: Amida Buddha's vow is especially directed at saving evil beings, who have the greatest need. Used as a set phrase, not a general expression.
Shinran taught 'akunin shōki,' that Amida Buddha's primal vow saves even evil persons.
The teaching of akunin shōki holds that evil persons, rather than good ones, are the very object of salvation.
