• abrahmaṇyāḥ — neglectful of brāhminical culture
  a + brahmaṇya — un-Brahminical. The Yadus produced no one un-brāhminical. Gauḍīyas: brāhmaṇya in Vaiṣṇava reading is not caste but qualification — sevā, satya, dama. Kṛṣṇa's family upheld this universally.
• alpa-āyuṣaḥ — short-lived
  alpa (little) + āyus (lifespan). No Yadu was short-lived. Long life in Vaiṣṇava reckoning is a fruit of dharma — and a longer field for bhakti's practice. The dynasty's longevity is itself a piece of bhakti's accumulation.
• adhanaḥ — without wealth
  a + dhana — without riches. No Yadu was destitute. Gauḍīyas read this not as praise of mundane wealth but as a sign of dharmic balance: artha rightly subordinated to dharma is naturally abundant.
• vīryāḥ — valor
  Plural of vīrya — potency, strength. The dynasty was full of vīrya. Gauḍīya theology: Bhagavān's family expresses His vibhūti through their progeny — vīrya is a divine inheritance, not a personal achievement.

No one in this family was poor, short-lived, weak, or negligent of brahminical culture. The Yadu line is the Bhāgavatam's portrait of dharma achieved at scale: aiśvarya, longevity, vīrya, and brāhmaṇya all together. Bhagavān's house keeps all four.
