Withdraw from outcast returning outside Ashram’s entrance (6)
I believe the answer is:
repeal
'withdraw' is the definition.
(I've seen this before)
'outcast returning outside ashram's entrance' is the wordplay.
'outcast' becomes 'leper' (leper is a kind of outcast).
'returning' says the letters should be written in reverse.
'outside' indicates putting letters inside.
'entrance' says to take the initial letters.
The initial letter of 'ashrams' is 'a'.
'leper' written backwards gives 'repel'.
'repel' going around 'a' is 'REPEAL'.
'from' acts as a link.
(Other definitions for repeal that I've seen before include "Annul by legislative action" , "Annul a law" , "reverse" , "reversal of act" , "Annul, rescind" .)
