I didn't say it is "the" premise of Buddhism. I said it is a premise of Buddhism.
It is.
The story of Shakyamuni Buddha achieving enlightenment after 49 days of meditation under the Bodhi tree is pretty well known. There, of course, are a lot more antecedents to contemporary Buddhist thought and ethics than that one incident, but it's fair to say it's a pretty core part of the historical tradition, and precedes essentially everything that came after.
For context in this discussion, I am a practicing Zen Buddhist.
