• darpa-upaśamanāya — for the subduing of pride
  Compound: darpa (pride) + upaśamana (subduing, calming). Bhagavān's cakra-action on Bāṇa's arms is named here as darpa-upaśamana — therapeutic, not retributive. Gauḍīyas read this as the proper Vaiṣṇava reading of every chastisement: it cools darpa.
• bāhavaḥ — the arms were cut
  Past participle of pra-√vṛj (to lop, cut off). Bāṇa's many arms — symbols of inflated agency — are pruned. Gauḍīyas note the symbolism: the asura's bāhu-bala (arm-strength, i.e. self-effort apart from Bhagavān) is what bhakti specifically chops back.
• bhārāyitam — having become a burden
  Denominative past participle from bhāra (burden) — 'made into a burden'. Bāṇa's army had grown into a bhāra. Kṛṣṇa repeats the avatāra-rationale from v. 27. Gauḍīyas read this consistency as the chapter's interior auditing: Kṛṣṇa and the Śiva-jvara agree on the descent's purpose.
• sūditam — destroyed
  Past participle of √sūd (to put to death). Kṛṣṇa uses sūdita of the army, not of Bāṇa himself — the verb's distribution preserves the chapter's grammar of mercy. Army: sūdita. Bāṇa: pravṛkṇa-arms-only.

A surgeon explains, after the operation, why each cut was necessary: 'Your arms were severed to reduce pride; your army was destroyed to lift the earth's burden.' Kṛṣṇa's pruning is purposive — every chinned limb has its diagnostic name.
