Sukta 4
अपां रसः प्रथमजोऽथो वनस्पतीनाम्। उत सोमस्य भ्रातास्युतार्शमसि वृष्ण्यम्
apā́m ráso prathamajó ’thó vanaspátīnām | utá sómasya bhrā́tā́sy utā́rśam ási vṛ́ṣṇyam ||
Thou art the Waters’ sap, first-born; yea, the very essence of the lordly Plants. Moreover thou art Soma’s brother; moreover thou art the virile, the bull-like might.
Rishi: Atharvan/Āṅgirasa (hymn-cycle attribution typical for AV 4th kāṇḍa charms)
Devata: Vanaspati/Osadhi-rasa (plant-essence), with Soma as paradigmatic correlate
Chandas: Anuṣṭubh (predominant charm-meter; pāda-structure consistent with AV usage)
