A few years back I had an interest in unreadable psyphers and communications, from the likes of number stations. And while no one other than the recipients can decode these messages, an important thing that can be not hidden is the frequency messages are sent. When messages are sent regularly, most intelligence services are not that interested, however if the tempo increases, then they become concerned.
You could apply this thinking to what is happening now, regarding our 'new light'.
Typically, a doctrine or view changes every now and then, and we get informed through a letter, a District convention talk or at a AGM. However the last 18 months has seen a level of change not seen since the 1980s and to me, this is the clearest indicator of a turmoil existing within the Governing Body.
Now, while we may not not know the real reason why the Governing Body has really flooded us with this quite radical 'new light' (at the moment), the volume of it, for me is more telling than the actual messages themselves..
