Dear DW forum
The Pali words "samudayo" ("arising") & "atthaṅgamo" ("settling") are found in many suttas, such as:
SN 22.5 wrote:what is the origin of form, feeling, perception, choices, and consciousness?
Ko ca, bhikkhave, rūpassa samudayo, ko vedanāya samudayo, ko saññāya samudayo, ko saṅkhārānaṁ samudayo, ko viññāṇassa samudayo?
It’s when a mendicant approves, welcomes and keeps clinging.
Idha, bhikkhave, bhikkhu abhinandati abhivadati ajjhosāya tiṭṭhati.
And what is the ending of form, feeling, perception, choices and consciousness?
ko viññāṇassa atthaṅgamo?
It’s when a mendicant doesn’t approve, welcome, or keep clinging.
Idha, bhikkhave, nābhinandati nābhivadati nājjhosāya tiṭṭhati.

AN 4.41 wrote:And what is the way of developing immersion further that leads to the ending of defilements?
Katamā ca, bhikkhave, samādhibhāvanā bhāvitā bahulīkatā āsavānaṁ khayāya saṁvattati?
It’s when a mendicant meditates observing rise and fall in the five grasping aggregates.
Idha, bhikkhave, bhikkhu pañcasu upādānakkhandhesu udayabbayānupassī viharati:
‘Such is form, such is the origin of form, such is the ending of form.
‘iti rūpaṁ, iti rūpassa samudayo, iti rūpassa atthaṅgamo;
Such is feeling, such is the origin of feeling, such is the ending of feeling.
iti vedanā, iti vedanāya samudayo, iti vedanāya atthaṅgamo;
Such is perception, such is the origin of perception, such is the ending of perception.
iti saññā, iti saññāya samudayo, iti saññāya atthaṅgamo;
Such are choices, such is the origin of choices, such is the ending of choices.
iti saṅkhārā, iti saṅkhārānaṁ samudayo, iti saṅkhārānaṁ atthaṅgamo;
Such is consciousness, such is the origin of consciousness, such is the ending of consciousness.’
iti viññāṇaṁ, iti viññāṇassa samudayo, iti viññāṇassa atthaṅgamo’ti.
This is the way of developing immersion further that leads to the ending of defilements.
Ayaṁ, bhikkhave, samādhibhāvanā bhāvitā bahulīkatā āsavānaṁ khayāya saṁvattati.

Therefore, the above suttas say samudayo is the wrong path and nirodho/atthaṅgamo are the right path.SN 12.44 wrote:And what, mendicants, is the origin of the world?
“Katamo ca, bhikkhave, lokassa samudayo?
Eye consciousness arises dependent on the eye and sights. The meeting of the three is contact. Contact is a condition for feeling. Feeling is a condition for craving. Craving is a condition for grasping....etc
And what is the ending of the world?
Katamo ca, bhikkhave, lokassa atthaṅgamo?

Feeling is a condition for craving. When that craving fades away and ceases with nothing left over, grasping ceases (tassāyeva taṇhāya asesavirāganirodhā upādānanirodho.... This is the ending of the world. Ayaṁ kho, bhikkhave, lokassa atthaṅgamo.
