I pick the prettiest part of the sky and I melt into the wing and then into the air, till I'm just soul on a sunbeam.

The speaker describes flight as an act of self-transcendence: attention fixes on “the prettiest part of the sky,” and the self dissolves from body (“wing”) into pure element (“air”) until it becomes “just soul on a sunbeam.” In Bach’s recurring spiritual-aviation imagery, flying is not merely technical skill but a metaphor for freedom, presence, and the shedding of limiting identities. The line suggests an ecstatic, almost mystical union with light and motion—an experience where individuality is not erased so much as refined into essence. It frames liberation as a choice of perception and surrender rather than conquest.
