• yadu-udvahaḥ — raiser of the Yadu dynasty
  Yadu (the lineage) + udvaha (one who carries, raises). One of Kṛṣṇa's most affectionate dynasty-names. Gauḍīyas read it as 'the One who carries the Yadus across,' tāraka-nāma in Yadu-rūpa.
• gurvyā — heavy / weighty
  Feminine of guru, agreeing with the club. The same word means 'teacher.' The Bhāgavatam often plays the pun: the Lord's heaviest blow is a guru's lesson.
• kaumodakyā — with Kaumodakī
  From kumuda (white night-lotus). Kaumodakī is Viṣṇu's eternal gadā, one of His four iconographic objects (śaṅkha, cakra, gadā, padma). The club here is not borrowed — it is His.
• stana-antare — between the breasts
  Locative of stana-antara (chest, sternum). The śāstric site of the hṛd, the heart — where the jīva and Paramātmā are said to reside together. Dantavakra is liberated through his own heart.
• na cacāla — did not move
  Na + perfect of √cal (to move, shake). Acala, the unmoving, is Kṛṣṇa's nature. The verb echoes Gītā 2.10 (prahasann iva) and 11.46 (sthitaḥ sva-mahimni) — His stillness in conflict.

Kṛṣṇa's Kaumodakī club is named for the kumuda, the white night-lotus — it gives joy. When this club strikes Dantavakra's chest, it is a flower delivering death. The Lord's weapons are continuous with His ornaments; even the killing-blow is a kind of garlanding.
