1. Christian wrote, “I think it’s not really correct as the example of that person who was Sotapanna but didn’t believe it even if Buddha said so,.”
– Does the above sutta say that Susima was a Sotapanna? If so, please quote that verse.
– What I read was that Susima was not a Sotapanna. He had the wrong view that all Arahants would have supernormal powers, could read other people’s minds, etc.
2. Now, Christian’s request to clarify what is meant by the verse, “Pubbe kho, susima, dhammaṭṭhitiñāṇaṁ, pacchā nibbāne ñāṇan”ti.”
It says that one needs to first understand how to establish oneself in the Dhamma (Pubbe dhammaṭṭhitiñāṇaṁ) before being able to become a Sotapanna, i.e., “pacchā nibbāne ñāṇan” or the “path to Nibbana” comes later.
– “Pubbe” means “beforehand” AND “pacchā” means “later” or “next”.
– “Pubbe dhammaṭṭhitiñāṇaṁ” means one needs to first get rid of the ten types of miccha ditthi and also understand that one needs to learn Dhamma from a Noble Person (i.e., the four conditions must be satisfied: “Four Conditions for Attaining Sōtapanna Magga/Phala“).
