God, an incarnation of Vishnu, returning to embrace new country (7)
I believe the answer is:
myanmar
'country' is the definition.
(Myanmar is an example)
'god an incarnation of vishnu returning to embrace new' is the wordplay.
'god an' becomes 'my' (I can't explain this - if you can you should believe this answer much more).
'incarnation of vishnu' becomes 'rama' (I've seen this before).
'returning' says the letters should be written in reverse.
'to embrace' indicates putting letters inside.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'rama' back-to-front is 'amar'.
'amar' placed around 'n' is 'anmar'.
'my'+'anmar'='MYANMAR'
Can you help me to learn more?
(Other definitions for myanmar that I've seen before include "Far East location" , "Country of SE Asia" , "Newer name for Burma" , "state since military regime" , "Country on the Bay of Bengal" .)
