Patna developed uplifting, inclusive Hindu school (7)
I believe the answer is:
vedanta
'hindu school' is the definition.
The definition suggests a singular noun which matches the answer.
'patna developed uplifting inclusive' is the wordplay.
'inclusive' indicates the answer is hidden within the clue (I've seen this in other clues).
'uplifting' is a reversal indicator.
'atnadev' is hidden within 'patna developed'.
'atnadev' reversed gives 'VEDANTA'.
Can you help me to learn more?
(Other definitions for vedanta that I've seen before include "particular philosophy" , "Hindu philosophy" .)
