Analysis of O Heart of Spring

O HEART of Spring!   
 Spirit of light and love and joyous day,   
So soon to faint beneath the fiery Summer:   
Still smiles the Earth, eager for thee alway:   
Welcome art thou, soever short thy stay,           
Thou bold, thou blithe newcomer!   
Whither, O whither this thy journeying,   
 O heart of Spring?   

O heart of Spring!   
After the stormy days of Winter’s reign,           
When the keen winds their last lament are sighing,   
The Sun shall raise thee up to life again:   
In thy dim death thou shalt not suffer pain:   
Surely thou dost not fear this quiet dying?   
Whither, O whither this thy journeying,           
 O heart of Spring?   

O heart of Spring!   
Youth’s emblem, ancient and unchanging light,   
Uncomprehended, unconsumed, still burning:   
Oh that we could, as thou, rise from the night           
To find a world of blossoms lilac-white,   
And long-winged swallows unafraid returning…   
Whither, O whither this thy journeying,   
 O heart of Spring?
