help translation

[kxavier]

Hi, i was wondering if i could get some help in a translation for a quote from Marcus Aurelius.

« Nowhere can man find a quieter or more untroubled retreat than in his own soul. »
Marcus Aurelius

any help would be greatly appreciated, thanks in advance to anyone who can help me.

[MatthaeusLatinus]

Hi, you've already been given a good suggestion in another forum.

[DiscipulusAnonymus]

Another minor translation question...
In English, when we say something like "I know how you must be feeling", the sense of "must" is different than it is in a sentence like "Your fears must be faced" or the classic "Carthage must be destroyed". In the first, no sense of necessity is implied. At first glance, it doesn't seem quite right to use the same future passive participle construction there. Is this something a Roman would have said or would he have used another phrase to express his condolences?
