In Theravāda-Buddhism, we understand a thing by its conditions and effects, so in Dī.A. (sumaṅgala.2) Mahāsatipaṭṭhānasuttavaṇṇanā Satipaṭṭhāna-Udesavaṇṇanā:
The practitioner have to comprehend a mind by 1. its object, governer-object, governer-mental-factors, co-nascence-conditions, state, Kramma, resultants, Kiriya, etc., 2. impermanent, etc., and 3. in citta-anupassanā-satipaṭṭhāna "mind has passion", etc.
According to above explanation, the practitioner should have understood 8 Lobha-Mind-Arising, lobha-cittuppāda, with their conditions and effects in the dependent origination cycle to catch arising caving.

The path of purification, aggregate chapter, consciousness (90) (91) (92):
Tattha lobhamūlaṃ somanassupekkhādiṭṭhigatasaṅkhārabhedato aṭṭhavidhaṃ.
Ñ(XIV,90): II. (a) Herein, (22)-(29) that rooted in greed is of eight kinds, being classed according to joy, equanimity, [false] view, and prompting,
Seyyathidaṃ, somanassasahagataṃ diṭṭhigatasampayuttaṃ asaṅkhāraṃ sasaṅkhārañca, tathā diṭṭhigatavippayuttaṃ.
Ñ: that is to say: (22) when accompanied by joy it is either associated-with-[false-] view and unprompted, or (23) prompted; or (24) it is dissociated-from-[false-] view and likewise [unprompted or (25) prompted];
Upekkhāsahagataṃ diṭṭhigatasampayuttaṃ asaṅkhāraṃ sasaṅkhārañca, tathā diṭṭhigatavippayuttaṃ.
Ñ: and (26) when accompanied-by-equanimity it is either associated-with-[false-] view and unprompted, or (27) prompted; or (28) it is dissociated-from-[false-] view and likewise [unprompted, or (29) prompted].
Yadā hi ‘‘natthi kāmesu ādīnavo’’ti (ma. ni. 1.469) ādinā nayena micchādiṭṭhiṃ purakkhatvā haṭṭhatuṭṭho kāme vā paribhuñjati, diṭṭhamaṅgalādīni vā sārato pacceti sabhāvatikkheneva anussāhitena cittena, tadā paṭhamaṃ akusalacittaṃ uppajjati.
Ñ(XIV,91): (22) When a man is happy and content in placing wrong view foremost of the sort beginning 'There is no danger in sense desires' (M.i,307), and either enjoys sense desires with consciousness that in its own individual essence is eager without being urged, or believes auspicious sights, etc., have a [real substantial] core, then the first kind of unprofitable consciousness arises;
Yadā mandena samussāhitena cittena, tadā dutiyaṃ.
Ñ: (23) when it is with consciousness that is sluggish and urged on, then it is the second kind.
Yadā micchādiṭṭhiṃ apurakkhatvā kevalaṃ haṭṭhatuṭṭho methunaṃ vā sevati, parasampattiṃ vā abhijjhāyati, parabhaṇḍaṃ vā harati sabhāvatikkheneva anussāhitena cittena, tadā tatiyaṃ.
Ñ: (24) But when & man is happy and content only, without placing wrong view foremost, and indulges in sexual intercourse, or covets others' good fortune, or steals others' goods, with consciousness that in its own individual essence is eager without being urged, then it is the third kind.
Yadā mandena samussāhitena cittena, tadā catutthaṃ.
Ñ: (25) When it is with the consciousness that is sluggish and urged on, then it is the fourth kind.
Yadā pana kāmānaṃ vā asampattiṃ āgamma aññesaṃ vā somanassahetūnaṃ abhāvena catūsupi vikappesu somanassarahitā honti, tadā sesāni cattāri upekkhāsahagatāni uppajjantīti
Ñ: (26)-(29) But when the consciousnesses are devoid of joy in these four instances through encountering no excellence in the sense desires, or through want of any such cause for joy, then the remaining four, which are accompanied by equanimity, arise.
evaṃ somanassupekkhādiṭṭhigatasaṅkhārabhedato aṭṭhavidhaṃ lobhamūlaṃ veditabbaṃ.
Ñ: So that rooted in greed should be understood as of eight kinds, being classed according to joy, equanimity, [false] view and prompting.

See: Abhidhmmatthasaṅgaha Chapter 2 for a brief explanation, and see the path of purification for the explanation in detail.
The pre-nascence matters of lobha-minds are Hadayavatthu and Hadayavatthu has its own Co-nascence as well.
The practitioner also has to know the dependent origination as well.
It's almost impossible to understand all of that knowledge with no mistaking by one's self without Jhāna meditation and the professional master's taking care. When I ask the teacher of Pa-Auk about mental factors, he answered me whether I have to meditate Jhāna to get the answer. That's why I often recommend Pa-Auk.
