Based on and believing the surface, dense mind, we are accustomed to seeing walls and assume they naturally exist within as well as without us. Assuming they are real, we paint them, dress them or bring them down, building new ones in their place, because we have never imagined a life without them. We thus give all our attention, placing our energy on our seeming reality. This focused perception keeps us in isolated structures.
The walls are made of our belief systems, which form structures that we are too afraid to get out of. How do we tear down the whole wall structure at once, without needing to discover and recover every single brick that we used to put it together in the first place?
It is possible.
