Who is currently "holding" that truth?
Sadly, there will always be 'gate keepers', at least in civilizations current installation; and there will be ones that 'hold' onto truth, but in reality sell remedies for a price.

Who is really holding truth -the historical part in me says anyone who 'wins' in the end and this is very problematic; the other part says those who bring light to darkness and that is my hope
This dovetails into the second question
Who gets to reveal it to us? My hope is truth an no sugar coating

How does it get revealed?
Good question. My hope is it happens in a flash and is not a slow drip, or something where we have to say 'get on with it'
