Yes. Lang’s description requires a good understanding of Paticca Samuppada.
You can see that most current translators of Paticca Samuppada from Pali to English do not understand these necessary detailed explanations.
– See, “Distortion of Pāli Keywords in Paṭicca Samuppāda”
They simply translate “avijjā paccayā saṅkhārā, saṅkhāra paccayā viññāṇa,” as “Ignorance is a condition for choices. Choices are a condition for consciousness.” Then they translate the Patiloma (Reverse) Paticca Samuppada of “avijjā nirodhā saṅkhāra nirodho, saṅkhāra nirodhā viññāṇa nirodho” as “When ignorance ceases, choices cease. When choices cease, consciousness ceases.”
– That does not make sense since an Arahant would still generate saṅkhāra and would still have consciousness!
– They need to explain that the niddesa version of Paticca Samuppada is, “avijjā paccayā abhisaṅkhārā, abhisaṅkhāra paccayā kammaviññāṇa,” Several other terms need to be expanded.
– Then, they need to further explain each term in detail, as I pointed out in my earlier post.
