Sama Veda — Pūrvārcika, Mantra 4

{ "prastava": "Brief stobha ignition preparing a ‘striking’ udgītha.", "udgitha": "agnir vṛtrāṇi jaṅghanat (core victory statement)", "pratihara": "draviṇasyur vipanyayā (links victory to prosperity and praise)", "upadrava": "samiddhaḥ śukra āhutaḥ (kindling/brightness/feeding—stabilizing after action)", "nidhana": "Collective cadence sealing cleared space.", "structure_notes": "The mantra’s three semantic movements (victory → motive/praise → state of kindling) fit neatly into the five-part sāman architecture.", "singer_assignments": "Udgātṛ leads the victory line; Pratihartṛ answers with the causal phrase; all join the final stabilizing cadence." }

{ "gloss_summary": "Sāyaṇa interprets vṛtrāṇi as obstructive agencies that impede the sacrifice and its fruit; jaṅghanat as repeatedly crushing those impediments. draviṇasyuḥ is explained with reference to seeking/bringing draviṇa (wealth/means), and vipanyayā as praise/adoration that kindles Agni; samiddhaḥ, śukraḥ, āhutaḥ describe Agni’s enkindled, bright, oblation-fed state.", "ritual_interpretation": "A mantra of vighna-nāśa: clearing obstacles to ensure the yajña proceeds and yields draviṇa (ritual prosperity).", "theological_insight": "Agni’s brightness is not inherent alone but ritually co-produced: praise and offering kindle him, and the kindled Agni in turn breaks obstruction—reciprocity of yajña.", "etymology_highlights": "jaṅghanat (intensive/repetitive action); vipanyayā from √van/√pan nuances of praise; āhuta from ā-√hu (to offer)." }
