For those teachers (and pupils & parents) preparing for a few sleepless nights ahead of the return to school, here's a bedside poem that might help:
heaven laughs
and the earth dances
the Sun, Moon and stars
wrap themselves
in a curtain of silver.
nothing is done
and nothing can be
so fall asleep or stay awake
- it won't change a thing
By Yu Jinghai, taken from 'A Scatter of Light in he Summer Sky: Poems of the Tao'
