Song: Ruk Gaya Aankh Se Bahta Dariya (This river from my eyes has suddenly stopped (flowing))
Artist: Ghulam Ali Genre: Ghazal.
How did this running stream of tears suddenly stop flowing. He's trying to say that he has been crying so much (like a running stream or river), and asks how it suddenly stops? He's been crying so much that he doesn't even get tears anymore.
