'Even so, there are some basic guidelines that have proved practical for many. They are frequently cited by grief counselors, and they echo timeless principles found in an ancient book of wisdom, the Bible.'
They mention grief counsellors but then don't recommend you see one. Instead they take it upon themselves to distill the advice given by the experts and tag on a scripture with it.
I can't decide if it's arrogance, they know better than the experts or fear that JWs getting professional help will find out that the real world isn't so bad, there are compassionate people out there. It's probably both!
