I may not have discussed the difference between kamma bhava and uppatti bhava. It could have been mentioned in some posts, but I wanted to make sure.
So, I have added #13 to the post, “Bhava and Jāti – States of Existence and Births Therein”
13. All kammic energies accumulate in the kamma bhava. Just like any other energy, it will fade away with time, even though that will take billions of years. But, of course, new kammic energies are being accrued as old energies fade.
– It is at the cuti-paṭisandhi moment (grasping a new bhava) that part of the kammic energy in kamma bhava becomes “uppatti bhava” leading to the new existence.
– As a Noble Person moves up in magga phala, less kamma bhava (i.e., accumulated kammic energy) will be able to contribute to uppatti bhava. At the Arahant stage, there will be no uppatti bhava, since an Arahant will not have any more uppatti. Even though the kamma bhava for that Arahant will be still there, it will not become a uppatti bhava.
