“The mind that perceives the limitation is the limitation” is not a quote from the Buddha. It’s neither in the style of the early Nikāya scriptures (of which the Pali Tipitika/Canon is the best-known example) nor in the style of the later and more literary Mahayana Sutras.
The language and phrasing are far too contemporary for this to be from the Buddha.
Unfortunately I don’t know the ultimate origin of this quote. So far I haven’t found any instances of it occurring before 2012, which suggests that it is in fact of modern origins.
Could it be from C.S. Lewis ?
Is that a random guess, or do you have reason to believe that Lewis said this?
What if a present-day buddha said it? Or do buddha’s only exist in the distant past?
When a quote is attributed to “the Buddha,” this means the historical Buddha, Gautama.
Technically it’s not possible for there to be a present-day Buddha because a Buddha is someone who rediscovers the way to enlightenment at a time when it’s been lost. Since the way to enlightenment is still open, anyone who becomes enlightened is not a Buddha. Also such a person would have a name, and so we would attribute it to them.
Bruce lee?
Bruce Lee died in 1973, and in my previous researches I couldn’t find an instance of this quotation prior to 2012, so unless Lee was speaking from beyond the grave, it’s not likely it was him. (Or maybe there are earlier citations I haven’t found, or forms of the quote with different wording. It’s hard to say!)
