Dosakhayo asked: “So, the altered rupa is bahidda rupa, and cakkuvinneyya rupa is ajjhatta rupa?”
Yes. That can be understood as follows.
1. The “Cakkhuñca paṭicca rūpe ca uppajjāti cakkhu viññāṇaṃ“ includes both the bahiddha viññāṇa and the ajjhatta viññāṇa stages.
2. In #10 of that post, one way to describe the gradual attachment process (within a citta vithi) is stated: “Kāma dhātuṁ, bhikkhave, paṭicca uppajjati kāma saññā, kāma saññaṁ paṭicca uppajjati kāma saṅkappo, kāma saṅkappaṁ paṭicca uppajjati kāmacchando,..” Here, ““Kāma dhātuṁ, bhikkhave, paṭicca uppajjati kāma saññā” represent the bahiddha viññāṇa. Then, “kāma saññaṁ paṭicca uppajjati kāma saṅkappo” is the ajjhatta viññāṇa stage. That ajjhatta viññāṇa stage will occur for anyone with kāma rāga anusaya/samyojana, i.e., anyone below the Anagami stage.
3. That same process is described differently in the “Chachakka Sutta (MN 148)” (as described in the other post I mentioned “Indriya Make Phassa and Āyatana Make Samphassa”) as “Cakkhuñca paṭicca rūpe ca uppajjāti cakkhu viññāṇaṃ, tiṇṇaṃ saṅgati phasso.”
4. Both the bahiddha viññāṇa and the ajjhatta viññāṇa stages are included in the “Cakkhuñca paṭicca rūpe ca uppajjāti cakkhu viññāṇaṃ” step in that representation.
5. After the “kāma saññaṁ paṭicca uppajjati kāma saṅkappo” step comes “kāma saṅkappaṁ paṭicca uppajjati kāmacchando.” This is the second step (tiṇṇaṃ saṅgati phasso) in the other representation of the same event: “Cakkhuñca paṭicca rūpe ca uppajjāti cakkhu viññāṇaṃ, tiṇṇaṃ saṅgati phasso.” This step happens based on the “saṅ gati” present at that moment. Thus, even for the same person, the level of attachment depends on the state of the mind at that moment.
6. Note the difference in #2 and #5.
- #2: Regardless of the mindset, ANYONE below the Anagami stage WILL generate the ajjhatta viññāṇa.
- #5: However, a strong attachment to the sensory input with kāmacchanda may not happen for someone in a calm mindset trying to be mindful. Controlling this step with “mindfulness” (sila) can gradually eliminate kāma rāga anusaya/samyojana. Of course, cultivating wisdom (paññā) is also needed. As one cultivates paññā and sila, one’s mind will get to samādhi. That, in turn, will help further cultivate paññā and sila, and so on to elevate all three: sila, samādhi, paññā. Eventually, it is paññā that breaks the kāma rāga anusaya/samyojana. That is the Satipatthana/Anapanasati Bhavana!
