Any dukha or sukha felt in the current life is due to “panca upadana khandha” in previous lives. In that analogy, “poison was consumed” in a previous life, and one now reaps the results (vipaka).
Excellent Angle, Lal. Got it.
So, future suffering should be discriminated on two basis.
#1 possible future suffering within same jati.
#2 Future Suffering in future jati.
In addition differentiating with respect to dukkhā and dukha.
Dukkhā = all suffering (mental or physical) in case #2 + mental Suffering in case #1
Dukha = all physical suffering in case #1.
So, Human Arhant removed dukkhā, not dukha. Cause of that remaining dukha is in past.
