Religion like this welcoming suggestion (6)
I believe the answer is:
shinto
'religion' is the definition.
(Shinto is an example)
'like this welcoming suggestion' is the wordplay.
'like this' becomes 'so'.
'welcoming' is an insertion indicator (in sense of 'inviting in').
'suggestion' becomes 'hint' (hint is a kind of suggestion).
'so' placed around 'hint' is 'SHINTO'.
(Other definitions for shinto that I've seen before include "Ancestor-worshipping religion of Japan" , "faith" , "Japanese cult" , "Japanese ancestor-worshipping religion" , "Religious system" .)
