Beauty is included - a presence (8)
I believe the answer is:
charisma
'presence' is the definition.
(I've seen this in another clue)
'beauty is included a' is the wordplay.
'beauty' becomes 'charm' (charm is a kind of beauty).
'included' indicates putting letters inside.
'charm' enclosing 'is' is 'charism'.
'charism'+'a'='CHARISMA'
(Other definitions for charisma that I've seen before include "Personal magnetism, great charm" , "Attraction" , "Glamour" , "quality inspiring devotion" , "Compelling attractiveness" .)
