Edwin Ashurst sent this one along today:
Remembering a wrong is like carrying a burden on the mind
I don’t have much to say about it, unfortunately, because I haven’t yet been able to track its origins. The earliest reference I’ve found on the web dates from November 23, 2006. It’s in several books, but none I’ve found was published prior to 2010, and the words “Buddha is quoted as saying…” are used.
I’m fairly sure it’s not canonical (i.e. that it’s not from the Buddhist scriptures) just on the basis of the language.
There’s nothing wrong with the message, however. The Buddha is recorded as having said:
“He abused me, he struck me, he overpowered me, he robbed me.” Those who harbor such thoughts do not still their hatred. (Dhammapada, verse 4)
Clearly, harboring resentments is seen here as a kind of mental burden, but the suspect quote isn’t close enough to be even a bad paraphrase.
Hopefully more information about this quote will come to light in due course.
