Let our voice be heard in every corner of the world, for this life is merely a passing moment, dear friend.

This profound couplet is a declaration of absolute devotion. The poet, Mir Taqi Mir, is telling his beloved that his existence, his very life, is dedicated entirely to her. He asks her to make his voice the only sound she hears in this world, suggesting that his words and presence are the only things that matter to him. It's a powerful plea for singular attention and eternal connection.
