Kimpurusha is the name of a group of demi-gods in the heaven.
They are called so due to their resembblence with male human ( purusha) . They are, like the Gandharva race, good at music. Like the Kinnaras, they too are the divine bards. Many puranas mentioned Kinnaras as follwers of Indra in his wars against the demons. In Mahaabhaaratham too, this race is mentioned many times.
