Welcome to the forum, lucas.cambon!
Different people “see” Nibbana differently. But I am a bit puzzled by: ““In order to enter the Stream one MUST experience Nibbana, going beyond mind and matter and entering in the state of Nirodha where all the senses (including the mind) stop working.”
Is that something that you experienced or what you think it should be? If it a personal experience, it would be beneficial for others if you can describe what that experience was like.
Dukkha nirodha is “stopping future suffering”.
– Nirōdha comes from “nir” + “udā“, where “nir” meaning stop and “udā” is arising.
– Nirōdha could also mean, “ni” + “rōdha” where “ni” again is stop and “rōdha” refers to “wheel” or “wheeling” referring to samsāric journey.
At the first stage of Nibbana (Sotapanna), one “sees” why Nibbana should be realized (that repeated birth in the 31 realms is filled with suffering much more than temporary occasions of happiness) AND how that can be realized. It is like seeing “the path” to get to the destination (Nibbana or Arahanthood).
– In a mundane sense it is like “seeing” how 3 plus 5 is 8, without having to count with fingers. One just realizes the anicca nature of this world: That one can never maintain anything to one’s satisfaction.
Now one may start feeling bodily sensations on the way to get that moment or even after that phala moment.
– That is associated with getting to samadhi and in some cases jhana.
All senses stop working only in nirōdha samāpatti, which can be attained only after getting to at least the Anagami stage AND after cultivating all the Ariya jhanas.
