Yogi: When I practice on my own, how do I know that the awareness is increasing day by day?
Sayadaw: If you practice being aware continuously – you try and try to be aware moment to moment – sometimes awareness is present even without you trying to be aware. This means that awareness has gained momentum.
Now you try to be aware, try to be aware. Later, even without trying, awareness becomes present, awareness is already there. That means that awareness has become a habit.
You just need to check if awareness is present.
