finger is reality. in considering the finger you consider how moon is being represented. who is pointing this finger? toward what is my attention being directed and why should i look there? what does this finger want me to see? with these questions in mind one can choose to see as the finger sees, to look at the moon in another way, or to look at something else entirely.
while your security system is your eye from the inside, it is you finger from the outside.
what ring are you wearing?
