No relaxation, enclosing a direction for poetry (3-4)

I believe the answer is:

nor-east

I'm a little stuck... Click here to teach me more about this clue!

'direction for poetry' is the definition.
I can't tell whether this definition defines the answer.

'no relaxation enclosing a' is the wordplay.
'relaxation' becomes 'rest' (synonyms).
'enclosing' means one lot of letters goes inside another.
'rest' placed around 'a' is 'reast'.
'no'+'reast'='NOR-EAST'

Can you help me to learn more?

(Another definition for nor-east that I've seen is " Compass bearing".)

I've seen this clue in The Guardian.
