well mainly because it uses a kinda abstract/poetic concept that to explain something concrete. In order to understand the example you have to understand the little puzzle about the moon & the finger as well. Maybe I do understand the saying fully - maybe I don't fully understand the depth of that saying..? Now I'm confused about both!
Also using the term moon & luna. Are they the meant to be the thing? Where was luna mentioned in the saying? Is luna representing the moon?
I agree that the buddhist saying confused me at the start..
For the moon vs luna thing: For the line to be valid, 'moon' must be a datatype in C, so it can't be the name of the variable. It also makes sense literally because moon is a generalized body orbiting a planet whereas luna refers specifically to earths moon.
