Heaven is going into lots of shops (8)
I believe the answer is:
paradise
'heaven' is the definition.
(I know that heaven can be written as paradise)
'is going into lots of shops' is the wordplay.
'is going' becomes 'is' (I've seen this in other clues).
'into' indicates putting letters inside.
'lots of shops' becomes 'parade' (I can't justify this - if you can you should believe this answer much more).
'is' going inside 'parade' is 'PARADISE'.
Can you help me to learn more?
(Other definitions for paradise that I've seen before include "Felicity" , "What was lost to the poet" , "Shangri-La?" , "Eden; ideal place" , "Heaven, nirvana, Valhalla etc" .)
