Thank you for your response and clarification. I understand that avyakata does not mean “free of defilements” in every context, but in the specific case of vipaka-vinnana, it is ethically neutral. When the Buddha explains “sankhara-paccaya vinnanam” in dependent origination, the vinnana that arises due to past sankhara is a vipaka, the result of previous kamma. This type of consciousness is neutral and does not itself generate new kamma. It arises simply as the seeing, hearing, or knowing of an object. Since it is the fruition of past actions, it is not accompanied by raga (craving), dosa (hatred), or moha (delusion), which are the three unwholesome roots. Those defilements can arise only if, after the vipaka-vinnana, there is further reaction like attachment or aversion to the experience. Therefore, the consciousness at this stage is not defiled by the unwholesome roots. That is why the Buddha could describe it as avyakata and also include it in the dependent origination as conditioned by sankhara without implying that it is accompanied by greed, hatred, or delusion. I appreciate your pointing me to further readings and will study them carefully.
