• viprakurvan — harassing, troubling severely
  Intensive of vi- + pra- + √kṛ. The string of present participles (viprakurvan, dūṣayan) keeps the demon's activity ongoing — and then śrutvā ("having heard") cuts it. Song stops the harm.
• kula-striyaḥ — women of respectable families
  Compound: kula (lineage) + strī (woman). The asuric attack on kula-dharma is the Bhagavad-gītā 1.40–43 anxiety made visible. Dvivida is the very figure Arjuna feared producing through war; SB shows him already loose in the world.
• su-lalitam-gītam — very sweet song
  Compound: su (well) + lalita (graceful, charming) + gīta (song). The song is Balarāma's; Gauḍīyas note that even asuric ears bend to nāma-saṅkīrtana-like sweetness — Ajāmila's pattern, anticipating SB 6.2.
• girim-raivatakam — to Raivataka Mountain
  Raivataka — a hill near Dvārakā famed for Yādava pastimes. Sthāna-māhātmya: the place itself is pulled into the līlā as the stage for the slaying. Gauḍīyas insist dhāma is never inert backdrop but always participant.
• yayau — he went
  Perfect of √yā (to go). One verb seals the demon's fate: drawn by song, he closes the distance to his executioner. Bhagavān's call works in both moods — the bhakta runs to it, the asura is pulled to it.

Even the demon's ear cannot resist su-lalitam gītam — sweet song from Raivataka pulls him uphill against his own malice. Bhagavān's līlā has gravity; what comes for harm sometimes arrives within range of mercy.
