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 spirit meet and 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 disdained 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?
