It's dark because you are trying too hard.
Lightly child, lightly. Learn to do everything lightly.

Lightly, lightly – it's the best advice ever given me.
When it comes to dying even. Nothing ponderous, or portentous, or emphatic.
No rhetoric, no tremolos,
no self conscious persona putting on its celebrated imitation of Christ or Little Nell.

There are quicksands all about you, sucking at your feet,
trying to suck you down into fear and self-pity and despair.

Lightly my darling,
on tiptoes and no luggage,
not even a sponge bag,
completely unencumbered.
