This is the ultimate limit of love's sorrow, I then recalled my loving mother.

This poignant couplet speaks of love's ultimate sorrow. The poet describes reaching a point of such profound heartbreak and emotional distress that it feels like the absolute limit of what one can bear in love. In this moment of extreme vulnerability and pain, the most comforting and purest memory that surfaces is that of their loving mother. It beautifully captures how, even in the deepest despair caused by romantic love, the fundamental solace found in a mother's unconditional affection remains the ultimate refuge. It's a testament to the enduring power of a mother's love as a source of comfort.
