This couplet means that the deep sorrow causing tears to fall, or the complete breakdown of one's patience, are emotional states too profound to be expressed in words.

This profound couplet speaks to the unpredictable nature of the human heart. Amrut Ghayal suggests that emotions are so volatile that you cannot predict when tears will fall, nor can you predict when the strong facade of patience will finally crumble. It is a beautiful reminder that composure is often the hardest thing to maintain!
