There is joy in ruin itself; you haven't tasted that. For us, the world has become completely bitter.

This couplet suggests there's a unique kind of joy or freedom to be found in complete destitution or loss, a feeling that those who haven't experienced it can't truly understand. The poet implies that for them, the regular world, with its usual pleasures and pains, has lost its appeal and become bitter. It's a profound statement about finding contentment beyond material possessions. It conveys that when you have nothing left to lose, you gain a different, deeper perspective on life. It speaks to a deep spiritual detachment, where conventional worldly tastes no longer hold any sweetness.
