Love's Philosophy by Percy Bysshe Shelley

 
The fountains mingle with the river   
And the rivers with the ocean,   
The winds of heaven mix for ever   
With a sweet emotion;   
Nothing in the world is single, 
All things by a law divine   
In one another's being mingle—   
Why not I with thine?   
   
See the mountains kiss high heaven,   
And the waves clasp one another; 
No sister-flower would be forgiven   
If it disdain'd its brother;   
And the sunlight clasps the earth,   
And the moonbeams kiss the sea—   
What is all this sweet work worth 
If thou kiss not me?
