Spiritual, fictional bear (4)
I believe the answer is:
yogi
'bear' is the definition.
(cartoon character Yogi Bear)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for yogi that I've seen before include "Hindu meditator" , "Follower of a Hindu philosophy involving mind and body" , "philosophy student" , "Hindu teacher" , "Cartoon bear; Hindu ascetic" .)
