This quatrain by Ghalib encapsulates a quintessential theme of Urdu ghazal poetry: the profound embrace of sorrow and its consequence, sleeplessness. Ghalib, renowned for his philosophical depth and poignant expression of human suffering, here describes a heart so accustomed to pain that it has become 'dear,' leading to a state where sleep is an impossibility, almost a forbidden act. This reflects a common motif where the lover's anguish is so consuming that it alienates them from the mundane comforts of life.
