Almost objective state in which yoga is commonly practised (3)
I believe the answer is:
goa
'state in which yoga is commonly practised' is the definition.
'almost objective' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'objective' becomes 'goal' (I've seen this before).
'goal' with its final letter taken off is 'GOA'.
(Other definitions for goa that I've seen before include "part of subcontinent" , "Former Portuguese territory in India" , "Indian district" , "Former Portuguese colony on India's west coast" , "State of SW India" .)
