अब्रवीद्वचनं वीरो लक्ष्मणं लक्ष्मिवर्धनम्।

abravīt = spoke; vacanam = these words; vīraḥ = heroic Rāma; lakṣmaṇam = to Lakṣmaṇa; lakṣmi-vardhanam = who increased auspiciousness; eṣaḥ = here; lakṣmaṇa = Lakṣmaṇa; niṣkrāmati = comes; agastyaḥ = Agastya; bhagavān = the powerful; ṛṣiḥ = sage; audāryeṇa = by his nobility; avagacchāmi = I recognize; nidhānam = [to be] the source; tapasām = of austerities; imam = him.
Heroic Rāma spoke these words to Lakṣmaṇa who increased auspiciousness: “Lakṣmaṇa, here comes the powerful sage Agastya. By his nobility I recognize him [to be] the source of austerities.”
“By his nobility” means “by the greatness of his special prowess.”
