I think all art and creativity is meaningless, unless is it NPMR sourced.
Subjectively or objectively meaningless?
What exactly do you mean by "NPMR sourced"? Isn't the "source" just consciousness? NPMR is virtual...
to clarify, I believe real art occurs when the artist has opened the channel between mind (PMR) and subconcious (NMPR, higher self), by intent (meditation or consciousness shift for those who can) or by chance (volume + happy accident), and that which is there is incarnated here, on the canvas, in the poem, in the song, in the sculpture, in the prose, in the choreography, and so on...
in legacy language, I would call this becoming God's paintbrush, channelling the other world into this.
otherwise art is just internal mental PMR masturbation, with no value-added, which ends up as a downward spiral into mere shock value - excrement smeared on a crucifix anyone?
where I experienced this directly, in my yout, I would write a song every day, and once in a while the door would open and something would be created that did not come from me (PMR me), and that would be art, and the other was just flat stuff created by my mind.
maybe I am just imagining all this
