I received an email about amoha and panna requesting further clarification.
Amoha means “without moha”, and moha is a mind that is covered for one with 10 types of miccha ditthi; see, “Lōbha, Dōsa, Mōha versus Rāga, Patigha, Avijjā“.
So, there is a huge difference between amoha and panna. Panna requires comprehension of Tilakkhana.
