Love Changes One's Perspective on the Life One Led Before

The speaker of the poem seems to feel that whatever he and his lover were doing prior to finding one another was mere child's play, of no real importance. He suggests that they simply did whatever would bring them childish pleasures before. As an example, he seems to describe the young women he found beautiful prior to finding his current beloved; he desired them sexually, certainly, and he claims to have "got[ten]" them (by which I assume he means that he did have sex with them) but he realizes now that those feelings of lust and the so-called beauty of those women is merely a shadow of the love he now feels for his beloved and her far-superior beauty.

Love Makes Life Feel New and Exciting

The speaker says that he has no need to go adventuring or on a voyage of discovery; he is content to let other men find new worlds and follow maps to the far corners of the earth because he feels that he has an exciting world to share with his beloved. He has no need to leave home or her arms or her eyes because they have created a world together.

Real Love Can Never Die (Or, at Least, We Feel like It Cannot)

There are no fickle seasons of love, as there are in the world, and there are no dangers in its exploration as there are when one explores the natural world. Whatever "love" does die was not love to begin with; perhaps one partner loved more than the other and so they were not "mixed equally," a requirement for true and lasting love like the kind the speaker possesses with his beloved. No, for this speaker and his beloved, they "Love so alike" that he believes their love with never perish from the earth.
