 Early Vedic notions about the authorship of the Vedic hymns are different from philosophical views. Vedic hymns use words like kāru (“craftsman”) to describe the poet, and the act of producing a hymn is described as (Ṛgveda 10.71.2): “Like cleansing barley with a sieve, the wise poets created the speech with their mind”. The poets of the Vedic hymns are also called mantrakṛt (“makers of hymns”). Further, each hymn of the Veda is associated with a specific poet-priest and often with a family of poet-priests. But, already in the Ṛgveda, there are signs of the beginning of an impersonal conception of the origin of the Vedas. For instance, the famous Puruṣa-hymn of the Ṛgveda describes the hymns of the Ṛgveda, the formulae of Yajus and the songs of Sāman as originating from the primordial sacrifice of the cosmic being (Ṛgveda 10.90.9). This trend to ascribe impersonal origin to the Vedas gets further accentuated in the Brāhmaṇas and the Upaniṣads.
