Kaubera Tīrtha is a tīrtha (sacred bathing place) on the Sarasvatī river. It is the place where Kubera, the master of wealth and treasurer of the devas, did mahātapas (great austerity) to win his rule over all wealth and treasures.

Origin of the name

The place is called Kaubera because it is the place of Kubera’s first tapas (austerity). Through these austerities Kubera, the son of Viśravaḥ (Viśravās-suta), gained all his powers and possessions. The Mahābhārata tells that Kubera did mahātapas here. Through its fruit he gained the following.

Dhanādhipatya: rule over all wealth. The many great nidhis (treasure-hoards) sought Kubera out at this tīrtha and came to him here.
The friendship of Śaṅkara: the divine friendship of Maheśvara.
Consecration by the Maruts: the Marut-gaṇas performed his abhisheka (anointing) here.
The Pushpaka vimāna: the swift and famous flying vehicle, which moves at the speed of the mind and is carried along by haṃsas (swans). The devas gave it to Kubera here as a divine gift.
Daivatva and Lokapālatva: divine status and the office of lokapāla (guardian of one of the four directions).
His son Nalakūbara: Kubera received his son Nalakūbara at this tīrtha.

Balarāma at Kaubera Tīrtha

Balarāma visited this tīrtha during his pilgrimage along the Sarasvatī. He bathed here and performed the prescribed rites. He visited the grove where Kubera had done his great tapas, and he made generous offerings. Then he went on to the Bhadara-pācana tīrtha.
