Sleep Sweetly, And Sleep Sound

In searching for some songs that we have been doing in Mama+Toddler Yoga, I came across the most precious lullaby.

"By night and day we circle the sun, from year to year go round.
So Silently the planets revolve; sleep sweetly and sleep sound.
Now the Night bird sings of Saturn's rings, and the Heaven's starry crown, while You, my child, are circled in love; sleep sweetly and sleep sound."

I couldn't find an audio link so for now, we'll just have to make up our own tune.
