A power of Butterfly

My Cocoon tightens — Colors tease
I'm feeling for the Air —
A dim capacity for Wings
Demeans the Dress I wear —
A power of Butterfly must be —
The Aptitude to fly
Meadows of Majesty implies
And easy Sweeps of Sky —
So I must baffle at the Hint
And cipher at the Sign
And make much blunder, if at least
I take the clue divine —

Emily Dickinson
