Rishi: Atharvanic tradition (late book; r̥ṣi uncertain)
Devata: Vedamātā (Vāc/Śruti), Pāvamānī (Purifier), and Brahman (as locus: brahmaloka)
Chandas: Mixed; late Atharvanic triṣṭubh/jagatī-like expansions with enumerative cadence
Vedamātā is the Veda as Mother—Vāc/Śruti personified as the source of mantra-power, learning, and the distinctive radiance associated with Vedic life.
It asks for longevity and breath (āyus, prāṇa), family continuity (prajā), livelihood and resources (paśu, draviṇa), public honor (kīrti), and brahmavarcasa—sacral brilliance and authority grounded in Vedic purity.
That line functions as a ritual closure: after the blessing is granted, the invoked power is respectfully dismissed, sealing the effect and completing the act of invocation.
