Taking up clairvoyance before taking the lead from shelter (9)

I believe the answer is:

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

'taking up' is the definition.
(I've seen this before)

'clairvoyance before taking the lead from shelter' is the wordplay.
I cannot quite understand how this works, but
'clairvoyance' could be 'esp' (synonyms) and 'esp' is found in the answer.
'from' could be 'in' (I've seen this in other clues) and 'in' is found within the answer.
This may be the basis of clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for espousing that I've seen before include "Taking up", "Adopting".)

I've seen this clue in Sydney Morning Herald.
