“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.
