Yes. “avippaṭisāra” means “one would not be confused about the key concepts of Dhamma.”
– Of course, one may have many questions, but there would be no doubt about how births among various realms arise via anuloma PS and how they can be stopped from arising via patiloma PS.
– That leads to unshakable faith, i.e., “Avippaṭisāralakkhaṇā saddhā.”
P.S. I was trying to give the idea.
– “avippaṭisāra” means “not confused.”
– “lakkhana” means “quality/characteristic/feature,” depending on the context. May be “feature” is better suited here.
