Famous quotes related to boundary line:
“The boundary line between self and external world bears no relation to reality; the distinction between ego and world is made by spitting out part of the inside, and swallowing in part of the outside.”
—Norman O. Brown (b. 1913)
“Music is your own experience, your own thoughts, your wisdom. If you don’t live it, it won’t come out of your horn. They teach you there’s a boundary line to music. But, man, there’s no boundary line to art.”
—Charlie Parker (1920–1955)
