This profound couplet speaks of self-respect earned through pain. Mir Taqi Mir suggests that the speaker has already endured countless hardships and struggles in life. Therefore, if the beloved has inflicted great cruelty, it is natural and justified that the speaker has lowered his standards of devotion. It is a declaration of emotional survival—a refusal to be perpetually victimized.
