If you read the last post or 3, we can take blockages as something like the opposite of the tools and props we set our lives up with in order to be able to see beyond the mundane and everyday.
Blindspots in our sphere of vision in that broader field of our lives.
This is closely interconnected with the idea of 'shadows' (Jung etc.) --- the 'dark' area of our lives where we don't want to look, and that we avoid by focusing on the parts of ourselves and our lives we can accept.
Here we can borrow Richard Rudd/Gene Keys' axiom: every shadow contains a gift.
The road blocks we run up against aren't just in the way, they're containers for the very material (we think) we're searching for in the more visible areas of our lives. The missing parts of the puzzle we hide from ourselves because they're associated with suffering.
These are not only things (patterns) that block certain areas of life from view, but patterns that stop us from viewing life as whole and interconnected, or as a broader space.
E.g. worries about money. The worry itself is caused by a pattern that blocks a broader view that would show us a more interconnected complexity of life.
Hence the boxes we unlock not only contain treasure, but they unlock layers that carry across the whole life space.
