The union of three vargas is called Uttama. Four vargas combined constitute a Gopura. The combination of five vargas is called Simhasana. Two vargas united form Parijata. The union of six vargas is called Parvathamsa. When a seventh varga is added to the Parvathamsa, the combination becomes Devaloka. An eighth varga joined to the seven already spoken of will make the combination Devaloka likewise. The combination of 9 vargas is Iravata.
