Dare I think for myself

[Leanne]

Do tell me, which one shall fall prey?
The ones whose devils tear at their throat
Setting fire to every sense and thought
Whilst whipping them to submission -- I'd suggest a more substantial image than just "submission", it's a bit vague

Or the ones who sit in comfort -- good contrast between stanzas
Of the body, mind, and spirit
As demons play friend, and council -- do you mean counsel, as in advocate? That would work as either noun or, in conjunction with the next line, verb
Distracting eyes with their sparkle -- I don't think "eyes" is required as "sparkle" is a visual term

Should we stand constantly aware? -- I think the question mark would be more correct at the end of this stanza -- and ending on a rhetorical question is a good persuasive device
Treating both as teacher, and foe
Whilst being self-mindful, and astute
Stand we fall prey only to self -- very awkward phrasing -- your last line should be your most powerful, not leaving the reader with a "huh?"

Hi Jae -- good ideas here, it just runs a little too far toward generalities and would benefit from some stronger imagery. It's great to follow your thought processes though, I'd be interested to see how this ends up.
