I emailed you my current understanding of paṭiccasamuppāda.
Due to this valid point, I copied and pasted my current (since I am still in the process of learning) understanding of paṭiccasamuppāda below too since it seems like a core issue that would be helpful to discuss in PM/by email with other potential kalyanamittas anyway.
Four Noble Truths
Problem: sadness (dukkha)
Cause: thirst (tanha)
End: extinguishment (nibbana)
Way to the End: way (magga)
Noble Eight-Limbed Way
Twelve Conditions of Conditional Occurrence
Aging, Illness, Death, and the rest of Sadness (dukkha)
The Buddha seems to identify the cause of sadness (dukkha) to be thirst (tanha).
The two extreme ways of trying to quench thirst seems to be indulgence and deprivation.
The commonality between these two extremes are that they attempt to quench thirst directly.
The middle way that the Buddha claims actually quenches thirst is the Noble Eightfold Path.
The Noble Eightfold Path seems to lead to understanding (panna), which attempts to quench thirst indirectly by clarifying misunderstanding (avijjā), which in turn quenches thirsts (tanha), which in turn extinguishes sadness (dukkha).
This is the way in which I currently understand the concept of paṭiccasamuppāda.
