Maṇimatī, also called Durjaya, was the city of the rākshasa king Ilvala in the Mahābhārata. The name Durjaya means “difficult to conquer”.

Agastya at Maṇimatī

Agastya Maharshi went to Maṇimatī with three kings, Śrutarvān, Bradhnāśva and Trasadasyu. He went to face Ilvala and ask him for wealth. Agastya had asked for dāna (gifts) from the three kingdoms. None of them had a surplus of income that could be given without harming the king’s people.

Ilvala had gathered huge wealth through his murderous ways. He alone had a true surplus, though it had come by adharma. So Maṇimatī was the end of Agastya’s bhikshā (begging) journey after the visits to the three kingdoms.

At Maṇimatī, Agastya ate the meal in which Vātāpi had been cooked, and he digested Vātāpi fully. This ended Ilvala’s deadly scheme for good.

After Vātāpi was digested and Ilvala gave way, the wealth of Maṇimatī was shared out. The three kings received it for their kingdoms, and Agastya received it for Lopāmudrā. (Mahābhārata, Vana Parva, Chapters 96–97)
