• mucukundaḥ iti khyātaḥ — known as Mucukunda
  Phrase: 'celebrated by the name Mucukunda.' The name unlocks identity; the rest of the chapter will be his speech under that name. Gauḍīyas note that he was famous before this moment for tapas, and after it for stuti — the chapter pivots his fame from kṣatriya to Vaiṣṇava.
• brahmaṇyaḥ — devoted to the brāhmaṇas
  From brahman + yaḥ — one who reveres the brāhmaṇa class and the brahminical principles. A standing royal virtue in the Bhāgavata: Ambarīṣa, Yudhiṣṭhira, Parīkṣit are all brahmaṇyaḥ. The trait predicts his later humility before Kṛṣṇa, whom he will treat as the supreme brāhmaṇa-bandhu.
• satya-saṅgaraḥ — true to his battle-vow
  Compound: satya (true) + saṅgaraḥ (vow, engagement, battle). Once he gives his word in war, he keeps it — the kṣatriya-dharma summed in two syllables. The same satya-niṣṭhā will reappear when he refuses every material boon Kṛṣṇa offers.
• ikṣvāku-kule — in the Ikṣvāku dynasty
  Compound: ikṣvāku (the solar-line founder) + kule (in the dynasty). The same dynasty as Rāma. Gauḍīyas relish that Mucukunda is therefore a kinsman of Bhagavān's previous avatāra — Rāma's lineage meeting Kṛṣṇa's person, generations apart.
• māndhātṛ-tanayaḥ — the son of Māndhātā
  Compound: māndhātṛ (the cakravartī of SB 9.6) + tanayaḥ (son). Patronymic placement; the Bhāgavata never lets a devotee float free of paramparā. Even the man who burnt Kālayavana with a glance is, first, somebody's son.

  His Holiness Bhanu Swami· English

A great oak that came up from the Ikṣvāku-root — the same lineage as Rāma, the same dynasty that Bhāgavatam's ninth canto traces with reverence. Mucukunda is named, lineaged and placed: son of Māndhātā, devoted to brāhmaṇas, true to his battle-vow. Bhāgavata pedagogy never abstracts a devotee from his soil.
