Find nature, find being. This is simplicity.
But this presupposes "nature" to be outside awareness. It is not. Such an idea is, like many, only a delusion of subjectivity. Birds and wildlife enter and cross the grounds; outside the pull of the Earth's gravity, one is weightless. The extent to which analysis has meaning is valuable, and beyond that, it is a pointless exercise, an obstacle to discernment. To lose consciousness of one's true nature is a failure of rationality.
Eliminate the excessive; broaden the focus, extend the senses, and understanding follows.
The composer would do well to begin creative endeavors with this thought in mind: out of the simple evolves the complex, yet complexity expands into simplicity.
