Gana
The word Gaṇa (Devanagari: गण), in Sanskrit, means "flock, troop, multitude, number, tribe, series, class" (Monier Williams's dictionary). It can also be used to refer to a "body of attendants" and can refer to "a company, any assemblage or association of men formed for the attainment of the same aims".
In Hinduism, the Gaṇas (Devanagari: गण) are attendants of Shiva and live in Kailasa. Ganesha was chosen as their leader by Shiva, hence Ganesha's title gaṇa-īśa or gaṇa-pati, "lord of the gaṇas".
The word "gana" can also refer to councils or assemblies convened to discuss matters of religion or other topics.
