From listening to some mindboggling Rob Burbea talks on dependent origination/cessation and the dependent part of dependent origination makes time look like it's only a concept (because you can infinitely slice time, so no time) and all time really is is a bunch of particles pushing against each other. Because there is no dividing line between moments of time (because one conceptual moment must touch another one) it makes dependent origination (which is often taught in a linear way) seem time dependent which it must not be.
Dependent origination is synonymous with emptiness, not cessation. Take time, linearity and particles out of the equation completely, they
are only concepts (mental fabrications) and cannot be found in direct sensate experience other than via mental imputation; the apparent linearity of experience which leads to the conceptualization of "time" is
entirely implied.
Understanding dependent origination/emptiness is understanding that no 'thing' actually exists, all we can ever experience are the six streams of sense consciousness which we conceptualize as seeing, hearing, etc.
Yeah so if I have ALS and I have no sensation left but I'm alive my consciousness would depend on what's left which would be mental-consciousness. All the other consciousnesses would disappear. Though that might take some time to remove memory imprints since people who have lost their legs sometimes project that they can move their toes but at some point that must fade.
That doesn't really work as an example.
If there was only mental-consciousness, there would still be the other four aggregates and the ability to perceive mental representations of the other sense-consciousness. I posted a thread a while ago about the five elements and the five aggregates which might also help a bit:
Aggregates & Elements: A Multi-Model OverviewI recommend checking out a guy called Greg Goode, he does some really good and clear stuff on emptiness and dependent origination which would probably clear up a lot of your confusion.
