Word Meaning
ख़ाक-दाँ
khaak-daan
Meaning
Ash-heap, dustbin; metaphorically, the material world or the grave.
Detailed Meaning
Literally, 'khaak-daan' refers to a receptacle for ashes or a heap of dust. In classical Urdu and Persian poetry, it frequently serves as a metaphor for the physical world (this earth) or the dark, confining grave. In the cited couplet, it represents the mortal world or grave where the refined, spiritual self becomes soiled with coarse earth.
Etymology
Persian: compound of 'khāk' (earth, dust, ashes) and the suffix '-dān' (receptacle, holder).
Usage
In the Urdu ghazal, poets often employ 'khaak-daan' with a tone of detachment to evoke the base, perishable nature of the mortal world contrasted with the spiritual realm.
Examples
What permanence can one seek in this transient dustbin of a world?
Departing the garden of spirit, we were trapped in this earthen realm.
