This couplet states that if whatever the mind wished for were to actually happen, the speaker would quickly transform into a river.

This beautiful line explores the difference between our heartfelt wishes and what truly happens in life. The speaker poetically says, "If everything I wished for in my mind came true, I would have become a river long ago." It reflects a deep, unfulfilled longing. Imagine wanting something so intensely, perhaps to be free-flowing, continuously moving, or to nourish others like a river does. The couplet subtly reminds us that while we may dream big and desire many things, reality often follows its own course, independent of our mere wishes. It's a poignant reflection on the limits of desire and the often-unpredictable journey of life.
