Northern Hemisphere
Week 8

The senses' might grows strong
United with the gods' creative work;
It presses down my power of thinking
Into a dreamlike dullness.
When godly being
Desires union with my soul,
Must human thinking
In quiet dream-life rest content.

Southern Hemisphere
Week 34

In secret inwardly to feel
How all that I've preserved of old
Is quickened by new-risen sense of self:
This shall, awakening, pour forth cosmic forces
Into the outer actions of my life
And growing, mould me into true existence.

—Translation by Ruth and Hans Pusch
