• bhramarikā — because of whirling around
  From √bhram (to whirl). The technical word for spinning-induced dizziness. Uddhava picks a child's-play image to illustrate a deep Sāṅkhya point. Gauḍīya: the chapter never abandons the cowherd vocabulary even at the height of doctrine — the analogy itself is rural.
• bhrāmyati-iva — (the ground) seems to whirl
  Verbal phrase: bhrāmyati (whirls) + iva (as if). The 'as if' marks the illusion. The earth is stationary; only perception spins. Gauḍīya: kartā-bhāva is similarly an 'as-if,' not a reality.
• citte-kartari — while the mind is the doer
  Locative absolute: when the mind is the actor. The agent is the mind, not the self. Gauḍīya bhakti-psychology: the sādhana of nāma-saṅkīrtana works precisely by reassigning the mind's activity to Kṛṣṇa, leaving the ātmā at rest as servant, not master.
• kartā-iva — (the self appears) as if the doer
  Substantive + iva: doer + 'as if.' The self appears to be doing what the mind is doing. Gauḍīya: this is the precise illusion that bhakti dismantles — not by denying the self but by removing the false attribution.
• aham - dhiyā — because of false ego
  Compound: aham (I) + dhī (thought, intellection), instrumental. The 'I-thought' — the technical name in Sāṅkhya-yoga for ahaṅkāra. Gauḍīya: this aham-dhī is precisely what the gopīs have lost; they think only kṛṣṇa-dhī.
• ātmā — the self
  Nominative of ātman. The same ātmā Kṛṣṇa called Himself in verse 4 (mām eva … ātmānam manasā gatāḥ). The verse threads its way back: the self that the gopīs found in Kṛṣṇa is the very self that, in false ego, mistakes itself for doer.

Like a child spinning who sees the ground spin, the false ego sees itself as doer when only the mind is moving. The kartā-bhāva is a perceptual illusion — and the gopīs, who have surrendered all doership, are simply the ones who have stopped spinning.
