Dhammā, Kamma, Saṅkhāra, Mind – Critical Connections
“However, unlike in the previous case in #4 above, that kamma viññāṇa (kamma bīja) does not go away.”
I think the sentence should be like this: However, ~, that dhammā created by kamma viññāṇa does not go away. Of course, kamma viññāṇa generates dhammā, but kamma viññāṇa and dhammā are not the same things.
Kamma Viññāṇa – Link Between Mind and Matter
“The KEY POINT is that kamma viññāṇa is not totally mental: The mind — when attached to something — will create energy (i.e., a kamma bīja or a dhammā) that will be recorded in the kamma bhava.”
So kamma viññāṇa is a creator, and dhammā is a creation.
