The Book I picked from the shelf is “The Participatory Mind” by Henryk Skolimowsky

The last line is:

In the grandeur that it requires”

Poem
Words when came were divine
the first and the last of the Lord will be
Of good  best  pure and kind
Of teaching in lines of rhyme
in softness of sound and stress
of intonation and incline
Grand is the language that will be
form of poems and poetry
writers will write and write
let it be in grand form,in the
grandeur that it requires to be.
