Meaning of saying

I suppose it means that in order to be happy you need to share happiness with someone else.

Happiness was born a twin means you will feel happiness twice. Once when you actually feel it and second when you share it with someone else.

Is my understanding correct?

I am not sure whether it means that, or whether it means that happiness "comes in pairs", i.e. it needs two people to be happy together.

Here's a bit more:

Don Juan, Canto II, Stanza CLXXII.

Both were so young, and one so innocent,
That bathing passed for nothing; Juan seemed
To her, as 't were, the kind of being sent,
Of whom these two years she had nightly dreamed,
A something to be loved, a creature meant
To be her happiness, and whom she dee

When something good happens in your life you are so elated, filled with joy and happiness, naturally you want to share it with another...

I think he is trying to describe a form of love, and as such, that you would need a relationship with another person to experience it and share the joy. In a way saying that you cannot produce that happiness by yourself?

"To Have Joy, One Must Share It; Happiness Was Born a Twin"
