salvation through Amida Buddha's power (Buddhist term)
The original Buddhist meaning: the belief in Pure Land Buddhism that salvation comes through the power (他力) and original vow (本願) of Amida Buddha, rather than through one's own efforts.
A 四字熟語 with a notable gap between its original Buddhist meaning and its everyday usage. In everyday Japanese, it is almost always used in sense 1 with a negative connotation. Buddhist scholars sometimes object to this colloquial usage, noting that the original meaning (sense 2) refers to a profound religious concept in 浄土真宗 (Jodo Shinshu Buddhism). The opposite concept is 自力 (relying on one's own efforts).
