民の主よ、ヴリトラを殺す者（Vṛtrahan）よ、戦いのただ中でわれらは汝の讃歌を高らかに宣べよう。牛群の中を行き（それを授ける）英雄、友にして最も慈しき者、攻め寄せ得ぬ者（advayuḥ）。

Aindra Sāman (generic; specific tune not stated in input)
{ "prastava": "Short, energetic prelude cueing a martial contour.", "udgitha": "Carries ‘prabho… vṛtrahan… bravāvahai’ with a pronounced peak.", "pratihara": "Responsive cadence—often felt like a ‘call-and-response’ stabilization.", "upadrava": "Describes Indra’s movement among cattle and his heroism.", "nidhana": "Closes with ‘sakhā suśevo advayuḥ’ as a protective seal.", "structure_notes": "The final triad (friend–gracious–unassailable) is well-suited to a broadened nidhana that shifts rasa from battle to shelter.", "singer_assignments": "Standard: prastotṛ opens; udgātṛ drives the proclamation; pratihartṛ answers; all seal the protective ending." }
{ "gloss_summary": "‘Vṛtra’ as obstruction (āvaraṇa) to waters/wealth and by extension yajña-success; vṛtrahan removes impediments. ‘goṣu’ interpreted as cattle-wealth granted to sacrificers; Indra is gracious friend and unassailable protector.", "ritual_interpretation": "Protective stotra: removes enemies of the rite and secures prosperity/dakṣiṇā.", "theological_insight": "Indra’s power is both destructive (of obstruction) and benevolent (friendship), indicating righteous force under ṛta.", "etymology_highlights": "vṛtra from √vṛ (to cover/enclose); advayuḥ = not to be driven/repelled." }
