There are actually ten terms in all; your two articles inexplicably omit the mind-consciousness-element (manoviññāṇadhātu).Lal wrote: ↑Sat Jun 30, 2018 2:08 amThat is not correct. A pure citta that starts arising in one's mind gets contaminated in 9 stages within a billionth of a second, and that contamination depends on the arammana and that person's gati.
I have given a reference in #4 of the post, "https://puredhamma.net/abhidhamma/pabha ... -bhavanga/", which is Patisambhidamaggapakarana (Part I, p. 360). That is from the Buddha Jayanthi Tipitaka. I am not sure how to match that page number with Sutta Central version.
None of the sources that you cite describe the ten terms as being stages in a citta's evolution. Nor do any other Pali texts describe them so.
On the other hand, many texts explicitly state that the terms are synonyms for citta. Indeed the author of the Nettipakaraṇa —which I understand is a text that meets with your approval— cites several of the terms for the precise purpose of illustrating what the word "simile" (vevacanaṃ) means. (See the Netti's Vevacanahāravibhaṅga, "Analysis of the Mode of Conveying Similes"; Nett. 53-4).
The very idea that a momentary citta might undergo some sort of change in character (e.g., a pure citta becoming impure, or vice versa) would contravene one of the most elementary premises of Abhidhammic momentarism, namely, that each momentary citta has but a single jāti. A citta of one jāti (e.g. a kusala citta) may arise, pass away and then be followed by a citta of a different jāti, but a citta does not undergo a change of jāti during the brief span of its existence.
