Inga was a girl born from the primordial cloud. Inga was mud. She married her brother Mu and they had a boy called Imbung (wind). When he was born he blew so strongly that he raised the cloud, his father, into the sky and dried up his mother, the mud. In this way heaven and earth were made. http://ignca.nic.in/ps_01004.htm Inga was also earth.
