PART OV THE REAL DEAL
With the Invisibles, in many Cultures and Ages, is related to Death. Death can also act as a kind of philter with strict rules, any person of good morals know. This also mean, besides any miracolous help, Spirits (like all Beings) develope a sort of relationship.
Then, the wild, hard and harsh part would be:
WHAT DO I HAVE LEARNED FROM YOU?
Ask that Youself and you won’t fail.
It just requires severe introspection not suitable for egotic and childish braindamaged.
Death has no mercy and is always equal.
Get respected before asking anything.
