Kubera, the treasurer of Gods, is also the king of Yakshas
and Kinnaras. He was the elder brother of Ravana – the demon King in the
Ramayana. Here is story as to how Kuber became the lord of Yakshas and
Kinnaras.
Sage Vaishravana had three sons – Kubera, Ravana and
Vibhishana. Kubera was the king of Lanka. But he was defeated by Ravana. The
demon king also took away all the wealth of Kubera including the aerial
vehicle, Pushpaka Vimana.
The displaced king roamed around the world and years later
he reached Kashi. Here he offered prayers to Shiva for several years.
Shiva always helped those whom the world shuns. Kubera was
short, with a big potbelly and had only one eye. The world was not kind to him
but Shiva was.
Shiva gave him several boons and made him the treasurer of
wealth of gods. He asked Kubera to go and live in the city of Alakapuri
in the Himalayas .
