O LOVE, let us part now!
Ours is the tremulous, low-spoken vow,
Ours is the spell of meeting hands and eyes.
The first, involuntary, sacred kiss
Still on our lips in benediction lies.
O Love, be wise!
Love at its best is worth no more than this--
Let us part now!


O Love, let us part now!
Ere yet the roses wither on my brow,
Ere yet the lilies wither in your breast,
Ere the implacable hour shall flower to bear
The seeds of deathless anguish and unrest.
To part is best.
Between us still the drawn sword flameth fair--
Let us part now!

Edith Nesbit
