Q is telling us that everything given to us should go onto a map to provide a 40,000' view of what's going on. Once we have that, then we can choose which direction to go (dig) to arrive at our desired destination (conclusions). Along the way we have to build the legend (symbols providing additional info). There is a sequence to the release of the info. The map is built in sections over time.
Read this from the bottom up. Might make a little more sense.
