O thought, what is life, and what is the intensity of the gaze? It is the death of the self, a suspicion of sin.

In this couplet, the poet, Allama Iqbal, poses a profound question about the meaning of life. He asks if life is merely thought or the intensity of a gaze. According to the poet, all of this is nothing but the suspicion of sin, which represents the death of the self (Khudi). It suggests that our existence is marked by a continuous, self-destructive feeling of guilt.
