suggests that accomplishing something previously impossible is now extremely easy, and the sky itself has become unrestrained or audacious.

This couplet is a masterclass in dramatic contrast. The first line, 'I achieved it equal to dust,' suggests an accomplishment that came from the lowest possible place, from nothingness. But the second line, 'The sky has simply become audacious,' elevates that achievement to cosmic proportions. It implies that the speaker's action or realization was so profound, so overwhelming, that it startled the very heavens. It speaks of a monumental defiance that shatters the natural order.
