You may write your name on sand or on your palm. We are so mad and wounded that we have neither a name nor a fixed abode.

This couplet beautifully portrays a lover's intense devotion. It says, 'You might write your name on sand or your hand, suggesting something fleeting or easily forgotten.' But then, the lover confesses, 'We are so utterly mad, so deeply wounded by this love, that we've lost our own identity, our name, and even our place in the world.' It means even a temporary mention of the beloved's name has such a profound effect that the lover becomes completely consumed, forgetting who they are and where they belong, lost in their adoration. It's a poignant expression of selfless, all-encompassing love.
