’T is you that are the music, not your song.
  The song is but a door which, opening wide,
  Lets forth the pent-up melody inside,
Your spirit’s harmony, which clear and strong
Sing but of you. Throughout your whole life long
  Your songs, your thoughts, your doings, each divide
  This perfect beauty; waves within a tide,
Or single notes amid a glorious throng.
  The song of earth has many different chords;
Ocean has many moods and many tones
  Yet always ocean. In the damp Spring woods
The painted trillium smiles, while crisp pine cones
  Autumn alone can ripen. So is this
  One music with a thousand cadences.

Once I freed myself of my duties to tasks and people and went down to the cleansing sea...
The air was like wine to my spirit,
The sky bathed my eyes with infinity,
The sun followed me, casting golden snares on the tide,
And the ocean—masses of molten surfaces, faintly gray-blue—sang to my heart...

Then I found myself, all here in the body and brain, and all there on the shore:
Content to be myself: free, and strong, and enlarged:
Then I knew the depths of myself were the depths of space.
And all living beings were of those depths (my brothers and sisters)
And that by going inward and away from duties, cities, street-cars and greetings,
I was dipping behind all surfaces, piercing cities and people,
And entering in and possessing them, more than a brother,
The surge of all life in them and in me...

So I swore I would be myself (there by the ocean)
And I swore I would cease to neglect myself, but would take myself as my mate,
Solemn marriage and deep: midnights of thought to be:
Long mornings of sacred communion, and twilights of talk,
Myself and I, long parted, clasping and married till death.
