Sound
I asked a friend
"When a tree falls in the forest,
and no one is there to hear it,
does it make a sound?"

He replied,
"There was a sound
when I was thinking of the question."

I replied,
"I just said there is no one there to hear it,
why did you put yourself there?"

Sound is defined by the hearer,
It is the vibration of air in your ear, in your mind,
that gives rise to hearing.

Reality is "defined" by its experiencer.
Delusion is "shaped" by its experiencer.
