Classic Poem

I wonder why my inlaid harp has fifty strings,
Each with its flower-like fret an interval of youth.
… The sage Chuang-tzu is day-dreaming, bewitched by but terflies,
The spring-heart of Emperor Wang is crying in a cuckoo,
Mermen weep their pearly tears down a moon-green sea,
Blue fields are breathing their jade to the sun …
And a moment that ought to have lasted for ever
Has come and gone before I knew.
