The instruction Neville derives from recurrence, and it is the only piece of conduct advice in the corpus that is grounded on a threat. Because you are on the wheel of recurrence, you will live this life again; so live this day so that your mind can store a past worthy of recall, because if you don't change it now, it will confront you tomorrow. The force of it is entirely in the mechanism: nothing is being punished and nobody is judging, but the material of the next round is what you are laying down now, and the only editor is memory. It travels with the doctrine of revision, since revision is how a past already laid down is changed before it is stored, and with the wheel itself (M508), which supplies the reason. About twelve lectures. Neville states it without softening the alternative - the wheel turns whether you repent or not, and you will come out as God either way; what repentance buys is not salvation but a better recording.
