This one was brought to my attention recently as a quote I haven’t written up. My correspondent was very suspicious of it, and in a way he was right: it’s not at all typical of how the early scriptures quote the Buddha.
It was however from a sutta (Buddhist scriptural discourse) that I know very well, although I’d characterize it as a good paraphrase rather than an actual quote.
It’s from the Karaniya Metta Sutta:
Just as with her own life
A mother shields from hurt
Her own son, her only child,
Let all-embracing thoughts
For all beings be yours.
You can find the entire sutta (which isn’t very long) on Access to Insight.
Lawrence Khantipalo Mills’ translation on Sutta Central is as follows:
Just as a mother at the risk of life
loves and protects her child, her only child,
so one should cultivate this boundless love
to all that live in the whole universe.
The original stresses the mother protecting rather than loving her child, so a better paraphrase would be “Love the whole world as a mother protects her only child.” Still, it’s not too far off as it stands. I can’t bring myself to call this “fake” but it’s also not an actual quote, so I’ve put it in my “fakeish” category. No disrespect is intended by this categorization.
