瑜伽師地論略纂 8.97

8.97

「或骨或瑣，或復骨隙」，且解：曰骨，謂骨餘處；瑣，謂骨相連處；或復骨瑣者，謂總合觀。

"Either bones, or a chain, or the gaps between bones": tentatively explained: "bones" refers to other parts of the skeleton; "chain" refers to the places where bones connect; "or bones and chain" refers to contemplating them together as a whole.
