Loreena McKennitt-,The Two Trees

"There, through the broken branches, go
The ravens of unresting thought;
Flying, crying, to and fro,
Cruel claw and hungry throat,
Or else they stand and sniff the wind,
And shake their ragged wings: alas!
Thy tender eyes grow all unkind:
Gaze no more in the bitter glass.
Beloved, gaze in thine own heart,
The holy tree is growing there;
From joy the holy branches start,
And all the trembling flowers they bear."
