Tu excitas ut...

This motto derives from Saint Augustine's Confessions: Bk 1, Ch. 1, Para 1.

Tu excitas ut laudare te delectet
quia fecisti nos ad te
et cor nostrum inquietum est
donec requiescat in te.

​You excite us so that we pleased to praise you
​because you made us towards you
and our heart is troubled
until it rests in you.​

Classic and simple: stimulus-response. What an artist engages in.
