• yadūnām kule — in the family of the Yadus
  Contiguous join (yadūnām + kule). Kula — clan, lineage. Gauḍīyas read Yadu-kula as Bhagavān's chosen vaṁśa, parallel to the Kuru-vaṁśa through which dharma was preserved. Stain to the Yadu kula is felt as stain to Kṛṣṇa's address.
• vicyutaḥ — who abandoned
  Past participle of vi + √cyut — to fall away. Same root as cyuti, falling. Pradyumna names battlefield-departure cyuti — a soteriological word in disguise; for the kṣatriya, leaving the field is its own kind of falling.
• klība-cittena — whose mentality is like that of a eunuch
  Contiguous join (klība + cittena). Klība — impotent, eunuch. The same word Kṛṣṇa uses to Arjuna in Gītā 2.3 (klaibyaṁ mā sma gamaḥ pārtha). Pradyumna throws his father's Gītā-word at his own driver — the family vocabulary recycles.
• kilbiṣāt — stain
  Ablative of kilbiṣa — sin, taint. In dharma-śāstra kilbiṣa is the impurity that requires prāyaścitta. Pradyumna names what his rescue has produced: a kilbiṣa-mark on the Yadu name. The driver's act is, in his view, a small adharma even though kindly.
• śrūyate — is heard of
  Passive of √śru. The same root as śravaṇa. Pradyumna's worry is precisely that the wrong thing about him will be heard. Śravaṇa is the medium of fame as well as of bhakti — both flow through the ear.

• What family or lineage honor do I carry, and how does it shape my choices?
• Where does that honor genuinely guide me, and where might it merely shame me?

Like a name passed down a long family of bell-clear ringers, suddenly fearing the soot of one dull stroke — Pradyumna grieves the stain to the Yadu line. The honor of one's vaṁśa weighs more than the body of one warrior.
