Rishi: Traditionally ascribed within RV 10.18 to a Vasiṣṭha-associated lineage (Anukramaṇī attribution varies in secondary traditions); the hymn functions as a funeral/ancestral rite text rather than a single-deity praise.
Devata: Primarily Mṛtyu (Death) is addressed/handled; secondarily the sacrificial community is instructed toward purification and life-increase.
Chandas: Triṣṭubh (predominant in this section of 10.18).
