1.
you reap what you sow; suffering the consequences of your own actions; brought it on yourself
A proverb meaning that one's misfortune or suffering is the result of one's own past behavior or mistakes. Literally, rust that comes from the blade itself.
A well-known proverb. The metaphor comes from a sword: if a blade is not properly cared for, rust (錆) emerges from the metal of the blade itself (身), not from an external source. Similarly, one's own troubles come from within — from one's own behavior.
Usage
Typically used as a predicate with だ, or in the pattern ～は身から出た錆だ. Often spoken with a tone of resigned acceptance or mild reproach. Can sound harsh when directed at others, so it is frequently used about oneself or in general commentary.
