What is a term for an attitude/life that eschews luxury or comfort?


A while back I had read an article (in English) online about an Japanese
ceramics artist and his work, with the writer describing the artist's rather
spartan furnishings as a result of his attitude or lifestyle that eschewed
luxury or comfort, allowing him to better focus on his art. Whether that was
actually true or not, he described it using a Japanese word, perhaps a zen
concept, explaining and using that idea to paint an ethereal picture of the
artist's dedication to his work. I don't know how much liberty he was taking
(if any at all) with the word he was using, but here I am asking if there's
anyone out there familiar with a Japanese word that encapsulates this
idea/concept.

**Added:** I had been scanning thru hundreds of images of Japanese ceramics
and checking into artists' background and then became fixated on some
fantastic examples of [金継]{きんつぎ} / [金繕い]{きんつくろい} and this is where I lost
where I was before when I can across that term I'm inquiring about. I don't
think I can make my way back (though I've tried) to that particular article.

In all honesty, I don't think I'd be able to give a yea/nay on the correct one
any more, even if saw it, but I appreciate all of the suggestions that have
been offered. I think, so far, that
[[質素倹約]{しっそけんやく}](https://jisho.org/search/%E8%B3%AA%E7%B4%A0%E5%80%B9%E7%B4%84)
probably best approximates what it was that I was looking for even though the
definition doesn't come close to how romantically the author of the piece
described it.
