To expand awareness is to unbound awareness; it is to remove boundaries that limit our awareness.
In REALITY, your awareness is UNBOUNDED.
We only THINK that our awareness is bounded. Unbounding and expanding our awareness is the process of discovering the truth about your awareness.
Discovering the truth means that you will see more and more the REAL nature of your awareness. You will do this by connecting with the reality. You will do this by connecting with your body wich is the part of the REALITY.
Remember that this process is automatic and effortless. You just have to ALLOW it to happen.
