1 is the best, 8 the lowest.
The kammic return in form of happy pleasure is largest for the spontaneous
and unprompted actions, that is done by own
choice & initiative, and not after

The delayed
future effect of all these mental states is happiness, joy
and pleasure!
There are in total 89 kinds of Consciousness!
