I believe the answer is:
'meditative exercise' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for yoga that I've seen before include "Hindu spiritual system" , "Hindu system of meditation and self-control" , "System involving physical and mental exercises" , "Spiritual exercise discipline" , "Hindu ascetic system" .)
