Nirutti is actually said to be one of the Ashta-dikpalas. Ashta-dikpala means guardians of eight direction. Thus Nirutti is said to be guarding the south-west direction. He rides on a lion. His weapon is called the Kundayudha. His consort is Durga. Some times taking Brahma as the centre they form the Navasandhi. ‘Nava’ mean nine and ‘Sandhi’ is directions. Other dikpalas are Indra, Agni, Varuna, Vaayu, Yama, Ishana and Kubera. These hastas are used in the Navasandhi kauthukams.
With reference to dance, Abhinayadarpanam says
Khatavacha shakataschaiva keertitau nirrtti karaha
