William Butler Yeats

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.
The changing colours of its fruit
Have dowered the stars with metry light;
The surety of its hidden root
Has planted quiet in the night;
The shaking of its leafy head
Has given the waves their melody,
And made my lips and music wed,
Murmuring a wizard song for thee.

William Butler Yeats, The Two Trees
