Enlightenment leads to turning out in Eastern dress (6)
I believe the answer is:
satori
'enlightenment' is the definition.
(Buddhist term)
'leads to turning out in eastern dress' is the wordplay.
'leads to' suggests taking the first letters.
'in' is an insertion indicator.
'eastern dress' becomes 'sari' (sari is a kind of dress. I am not sure about the 'eastern' bit.).
The initial letters of 'turning out' is 'to'.
'to' put into 'sari' is 'SATORI'.
Can you help me to learn more?
(Other definitions for satori that I've seen before include "sudden Buddhist enlightenment" , "Sudden enlightenment (Buddhism)" , "awareness all of a sudden" , "sudden awakening" , "enlightened state" .)
