U
Unapproachable grandeur and simplicity
Unaware of her bitter taunt
Under the vivifying touch of genius
Unearthly in its malignant glee
Unfathomed depths and impossibilities
Unforced and unstudied depth of feeling
Unspoiled by praise or blame
Unspoken messages from some vaster world
Unstable moral equilibrium of boyhood
Until sleep overtakes us at a stride
Untouched by the ruthless spirit of improvement
Upon the mountain-tops of meditation
Urbanely plastic and versatile
Uttering grandiose puerilities [puerilities = childishness, silly]
