I slightly revised it as follows:
9. Based on ANY sensory input and the uppatti bhavaṅga, a mind will start at a particular DEFILED STATE (with mano saṅkhāra) unless one is an Arahant. Even if an average human may not strongly attach to a sense input, “distorted saññā” is automatically generated; the reason is not realizing the anicca nature, but we will discuss that later.
The point is the following. Following is #1 in that post.
1. The Buddha described this difference in the “Sanidāna Sutta (SN 14.12)“: “Kāmadhātuṁ, bhikkhave, paṭicca uppajjati kāmasaññā, kāmasaññaṁ paṭicca uppajjati kāmasaṅkappo, kāmasaṅkappaṁ paṭicca uppajjati kāmacchando, kāmacchandaṁ paṭicca uppajjati kāmapariḷāho, kāmapariḷāhaṁ paṭicca uppajjati kāmapariyesanā.” OR “Attachment to kāma dhātu leads to kāma saññā, attachment to kāma saññā leads to kāma saṅkappa, attachment to kāma saṅkappa leads to kāmacchanda..and so on to kāma pariyesanā.“
- The first step, “Kāmadhātuṁ, bhikkhave, paṭicca uppajjati kāmasaññā” happens to all, including Arahants.
- The second step, “kāmasaññaṁ paṭicca uppajjati kāmasaṅkappo,” DOES NOT happen to an Arahant or Anagami (who have eliminated kama raga).
- The subsequent step, ” kāmasaṅkappaṁ paṭicca uppajjati kāmacchando” happens ONLY IF one gets strongly attached to the arammana. That leads to “tanha paccaya upadana” step in PS. That is when the “pancupadanakkhandha” starts. Thus, not all arammana lead to pancupadanakkhandha even for a puthujjana.
