Yogi: It appears that thoughts are from the brain and hearing is coming from outside to inside.
Sayadaw: Just happening. Hearing is happening. That’s enough – finished. Direction and place are concepts, they are not real. Hearing is real.
[Yogi’s note: Simply being known is defined as an object. One shouldn’t focus - without focusing one can know. When we focus, the mind is paying attention to the concept. When the mind pays attention to concepts, liking and disliking arise.]
