Is there a word for a positive, enriching type of escapism

Escapism is a valuable tool, especially in times of extreme stress, but to me seeking escapism one is not pursuing something that will enrich or bring growth to his/her life rather simply a way to avoid dealing with unpleasant realities. To me it never rises above being a distraction.

Is there a word for getting so lost in something that for lack of a better way of saying it, feeds one's soul, i.e. great music, theater, literature, visual art, etc?

I submit that no such word exists.

The American writer Ursula LeGuin recently wrote this: “The direction of escape is towards freedom. So what is “escapism” an accusation of?”

It’s from her collection of essays, No Time to Spare: Thinking About What Matters. More here: https://www.goodreads.com/book/show/33503495-no-time-to-spare

My point is that if such a word existed, then Ms. LeGuin would have proclaimed it forcefully.

Certainly there is nothing that answers the moral accusation implicit in calling something escapist, or which has gained currency in ordinary speech.

I think that "highbrowness" is as close a term as you may find to characterize the type of aspiration you seek to define: it does not make abstraction of "cold" intellectual aspirations and takes into account the humanities (ref.), the arts. This is, unfortunately, a term that has come to have negative connotations, and, surprisingly, it was considered to be a colloquial term (ngram) still 25 years ago (orig. US). Moreover, you might more properly say of someone that he/she is given to escapism rather than given to highbrowness as this latter appears not to be someone's more or less passing way to react to reality but a more profoundly ingrained behavioural trait. It is not to be confused then with a type of escapism as it is a way to be and not a feature patched onto your psychological makeup, which escapist aspirations tend to be.

• On my own terms -John Seymour - 1963 - Any show of highbrowness would, of course, have made me quite unacceptable to any of these boys; but any highbrowness in me was latent. I certainly did not try to suppress it — I did not know it was there. I read more than the other boys, ...

• The Nineteenth Century and After - Volume 112 - 1932 - ‎Extraits - The other highbrow novelists, such as Montague, Lawrence, Forster, Huxley, owe their ' highbrowness,' not to a scorn of being easily comprehensible, but to the intellectual calibre of their work ; they are also excellent and versatile stylists.
