From "The Book of Thel" by William Blake

O life of this our spring! why fades the lotus of the water,
Why fade these children of the spring, born but to smile and fall?
Ah! Thel is like a wat'ry bow, and like a parting cloud;
Like a reflection in a glass; like shadows in the water;
Like dreams of infants, like a smile upon an infant's face;
Like the dove's voice; like transient day; like music in the air.
Ah! gentle may I lay me down, and gentle rest my head,
And gentle sleep the sleep of death, and gentle hear the voice
Of him that walketh in the garden in the evening time.
