rajas रजस्

Definition: Denotes the region of the atmosphere between heaven and earth in the Rigveda and later. The atmosphere, like the sky (Div), is divided into three regions, but more normally into two, the ‘earthly’ (pārthiva) and the ‘heavenly’ (divya or divah). In some passages the word refers in the plural to the dusty fields on earth.
