In 6. Surusuruvaggo in the Sekhiyakaṇḍaṃ "milk-drinks/juice" and milk appear together:
Tena samayena buddho bhagavā kosambiyaṃ viharati ghositārāme. Tena kho pana samayena aññatarena brāhmaṇena saṅghassa payopānaṃ paṭiyattaṃ hoti. Bhikkhū surusurukārakaṃ khīraṃ pivanti.
As far as understanding: ...at that occassion a certain Brahman gave "milk-products/juice". The bhikkhus smacked and ate noisily while drinking milk.
So it seems, from this, that ilk is incl. in the "category"
payopānaṃ, at least in juice form.
That, if concluding here, in most seriouse way, would mean that milk (as raw products, not butter, not ghee) would fall under the group of the eight juices, yet not explicit mentioned as the "for seven days store-able tonics".
This means, as far as seeing, that consume of certain (at least liquidity) milk products are allowed to be consumed on the very day (not stored). Does my persons short investigation here fits to more skilled investigations of the Venerables? Bhante
Ariyadhammika ?
That will/would certain "shock" many who had blamed other for consuming milk in the afternoon.
My person has to confess that he might had adopted an incorrect "this is right, all else is wrong view" for longer as well, rebuking many when drinking milk in the afternoon (of course they thought it's one of the five tonics, but only in that far, seemingly wrong, not to speak of storing of low milk-drinks).
Please, if that seems right for all: May the Bhikkhus inform each other and possible ask for pardon. Maybe Bhante
Khemakumara or Nyom
Cheav Villa could also adress Bhante
Indaññāno and it would be of course a great gift if also Ven. Grandfather
Varado helps the community with his prove and investigation. Maybe Lok Ta even feels inspired to illustrate the words eloquent in the IGPT online.
Certain Burmese, Mahavihara, Dhammayut oders might have wrongly rebuked others for longer time, made it an issue for not doing the Uposatha together.
Of course my person does not know of what Commentaries may say, and as told, SEAsian (Thai, Khmer, Lao, Burma?) can not so be used, as people aren't familar with milk and it's products at all (Sri Lankan may have had milk culture).
May the topic help many toward a more refined accumulation of sense of self and even to get ride of on-group-holding-group-accumulating-view till even end off all fine kinds of mānaṃ.
