That emblem actually predates written history. The original meaning has been lost to time... All we know is that the triangles symbolize us monsters below, and the winged circle above symbolizes... Somethin' else.

He says that the original meaning has been lost to time, but that monsters are certain of the "being underground" part of it. Predating this will "all we know" is indicative that it's not sufficient information or some part of it was lost to time, like he said. They believe the "underground" part to be absolute fact, but they do not know the meaning of them being underground and the winged circle above. He then talks about the prophecy for a line in that same prompt.

While DT can't exist without SOULs, it can exist apart from SOULs. Remember Flowey? He can function without a soul, purely on DT and physical body. Or Chara? Chara can even return from the dead through DT that isn't in their body either - and isn't their own at all.

Hmm, I think I get it. I worked through it this way - maybe it will explain my thought process. ^^'

Flowey is a vessel, determination and some monster essence. All of the other vessels in the True Lab are just blank flowers. Also, it's fun chatting with you! Sorry if I come off as a grump - I'm tired right now, and I think getting sleep will help! Cheers! :D
