3 Zen, a term coming from zen [Buddhism](buddhism.md) (the word itself from *dhyana*, meaning *meditation*), means emphasis on meditation that leads to enlightenment; in a wider sense it hints on related things and feelings such as tranquility, spiritual peace, sudden coming to realization and understanding. In [hacker](hacking.md) speech *zen* is a very frequent term, according to [Jargon file](jargon_file.md) "to zen" means to understand something by simply meditating about it or by sudden realization (as opposed to e.g. active [trial and error](trial_and_error.md)).
