Yatus or Yatudhanas in Hinduism are evil spirits having
supernatural powers. They can take any form and are mentioned in the Puranas
and Mahabharata. They did have an independent existence but were later clubbed
with demons and Rakshasas. They usually dwell in forests and lonely places.
As per Vayu Purana there are twelve Yatus. Their parents are
Sage Kashyapa and his wife Surasi.
In the Mahabharata it is mentioned that Yatudhanas attack
sages and disturb their yajnas. They also take away materials collected for
sacrifices and domestic animals.
