I'd have to differ from the assessment that the previous commenters gave. There's an odd bunch of entries that are an awful lot like this one that came out when the site was still very new. It was obviously outside the norm to make (any) authorial intent explicit, but the aim is nonetheless straightforward. I might characterize this style of entry as a page ripped from a grimoire, or maybe a stray annotation that someone made during a study session (Zettelkästen, anyone?). Either one is right up my alley. If this entry were posted today, you might expect to find it quoted in its entirety at the start of a much larger work. (If it were up to me, this and its companion entry would be combined, with an eye to spare the redundant phrasing — but that's neither here nor there.) That's surely not to diminish what's here.
I would probably criticise the word choice, however, and swap "use" for something more active, and also try for a description with richer imagery overall.
