No worst, there is none (Hopkins)

    " O the mind, mind has mountains; cliffs of fall
Frightful, sheer, no-man-fathomed. Hold them cheap
May who ne'er hung there. Nor does long our small
Durance deal with that steep or deep. Here! creep,
Wretch, under a comfort serves in a whirlwind: all
Life death does end and each day dies with sleep".




"Under a comfort serves in a whirlwind" - what exactly does the penultimate line mean? Any ideas? A reference to Job, Prometheus, King Lear? Some screen shots from books found on the internet below (no mention of what the grammatical construction itself conveys or signifies).
