"As one might expect, having noted the emotional orientation of manas clearly expressed in the “Nasadiya” hymn [Hymn of Creation in Rigveda] — where it is said that desire (kama) is the original seed of manas — the most common function of manas in the Rg Veda is its function as the locus of a wide range of emotions."
