• amogha-gatiḥ — of unfailing power
  Contiguous compound: amogha (unfailing) + gati (course, effort). A divine epithet — His gati is amogha. Compare Bhagavad-gītā 9.31: na me bhaktaḥ praṇaśyati — His devotee's progress is also amogha. The grace and the giver share the same predicate.
• īśvaraḥ — the Supreme Controller
  From √īś. Repeating from verse 15 — there in the queens' lament, here in Śuka's exposition. The same Bhagavān whose absence the queens felt is the īśvara whose every act succeeds.
• ajījanat — He begot
  Reduplicated aorist of √jan — to generate. Bhagavān, who is aja (unborn), does janayati — He generates. The unborn one becomes the source of all generation: Gauḍīyas note this is svarūpa-śakti's playful contradiction.
• ātma-jān — sons
  Compound: ātma (self) + ja (born of). 'Self-born' — born of one's own body. The technical Sanskrit term for natural-born children. Gauḍīyas note: Kṛṣṇa's sons are ātma-ja, His own — not vibhūti expansions but genuine progeny.
• bhāryāḥ — wives
  Plural of bhāryā — that which must be maintained. The classical term for wife in dharma-śāstra. Bhāryā implies bharaṇa — full maintenance. Kṛṣṇa as supreme bharta supports them all without distinction.

Ten sons in each of His many wives — Bhagavān's effort never fails. Where ordinary householders strive and hope, Kṛṣṇa simply is amogha — His every endeavor lands. Householderhood at the level of aiśvarya is unstrained completion.
