According to dependent origination consciousness is sustained by namarupa and vice versa.
If I understand correctly, during cessation, once namarupa ceases, consciousness doesn’t have any ground to stand on so it also ceases.
How is it then possible for it to re-arise and for the meditator to re-emerge from Nibbana?
I understand an arahant still has a body, so there is a physical condition for consciousness, but what is the specific impulse that makes it possible for consciousness to re-emerge once it has ceased?
How does one not remain in a vegetative state until the body dies?
