Let us great Our Heavenly Mother with a song!
Here is a strophe from the a hymn from the Brigittine Divine Office, sung on the Feasts of Our Lady :
O Virgo fons laetitiae – Tu corda nostra marcida
Irriga rore gratiae – Sint ut virtute florida .
(O Virgin, fountain of joy – Soften our hearts
Irrigate them with the dew of grace – So that they would be flowery with virtue.)
