Author may have thought it was about Syd, but it's about ego dissolution.

In youth we chase approval, then fear the laughter of others rather than delight in it (we learn shame and guilt).

"You reached for the secret too soon, you cried for the moon."

Let maya unravel at its own pace, don't rush it or you'll get paranoid and fearful. Ego is dissolved by the light. If you get too precise, carried by

Blown on the steel breeze. becomes Rode on the steel breeze.

We're blown and tossed by life when we try to explain precisely, be clever, or avoid madness, or try to see and interpret visions, express yourself, put your self in prison of conditional love, approval, satisfaction, or peace

ego exposed by the light, when we let ego die, we shine.

If you watch both interviews on Syd from Waters, and Gilmour; you'll hear both mention this song very much is about Syd. Also mentioning influences throughout The Wall.

@machinebor The artist usually knows what a song is about, because (t)he(y) wrote the song.
