I think almost everybody will encourage the imprisoned to meditate ...about their imprisonment reason.
Joke aside, it's not uncommon to hear former convicts mentioning about "back then" having "time to think". The time (served) does that to a man, be that he either likes it or not. Meditation (exercise) and other forms of dealing with boredom are something that give someone immediate and/or cheap result. Being trapped and forced to think about our own life and about the real things in it, like the prehistoric cavemen next to their camp fire through the winter nights, have a chance to produce something more valuable.
