Ordinary's minds always see Phenomena, reality, as only one.
But everything is subset of 2 phenomena:
- Saṅkhata is Conditioned phenomena, impermanent, non-self - uncontrollable.
- Asaṅkhata is Unconditioned phenomena, permanent, non-self - uncontrollable. Nibbana.
The conditioned phenomena has uncountable types depend on the environment, situations, which is called Sabhāga & Ghaṭanā.
Sabhāga & Ghaṭanā is the complicated uncountable conditions of the conditioned reality.
The ordinaries must see, Ghanavinibbhoga, these qualifications to see the conditioned realities, really arising and vanishing, not imagination:
- SantatiGhana: Birthing reality is arising and vanishing more than trillion moments a second because of causes, but ordinary person imagine they all are same long living for 1 minutes or 1 days or one life.
- SamūhaGhana: Birthing reality is so small than atom or particle (paramāṇū's qualities), but ordinary person imagine they all are same one loaf for 1 minutes or 1 days or one life or forever.
- KiccaGhana: Each birthing reality has difference jobs/specifications/qualifications when they causing their effect together, but ordinary person imagine they all are same doing/doer for 1 minutes or 1 days or one life or forever.
- ĀrammaṇaGhana: Each mind and mind factors process has difference object, but ordinary person imagine they all has same object for 1 minutes or 1 days or one life or forever.
Each reality is conditioning uncountable other realities. Each conditioned reality, except Nibbana, is conditioned by uncountable other realities.
For the example:
While we are reading now, only a second of only one reader included trillion mind moments, trillion objects, uncountable sense organs [very smaller than atom], not sense organs, etc. These are uncountable conditioning phenomena and conditioned phenomena. And we still are not talking about one's other seconds, others' minds, others' objects, others' sense organs, others' other moments, etc. So uncountable is uncountable. So typing, grouping are for easier to study, not for attaching on grouping.
The main core of the Buddha's teaching is Meditation for Really Finishing of Arising and Vanishing, DhammaCakkaṃ.
So the question is unfinished until you asking about your main meditation object from your meditation teacher. Make the focus on Meditation for Really Finishing of Arising and Vanishing. Do not focus on knowledge only. It is wasting this most valuable time.
