According to my knowledge, milk is considered in the vinaya as a food and not as an allowable 'drink' which can be consumed in the afternoon.
Then the other day a Thai monk showed me a sutta in the Khuddaka Nikaya, Mahāniddesa, Tuvaṭakasuttaniddesa which says that Buddha allowed beside of the usual 8 allowable drinks (mango juice, seedless banana juice, ...) also 8 other drinks of which the last one is MILK!Mv.VI.34.21 contains an allowance for the five products of the cow: milk, curds, buttermilk, butter, and ghee. The Commentary mentions that each of these five may be taken separately—i.e., the allowance does not mean that all five must be taken together. Milk and curds are classed as “finer staple foods” under Pc 39, but in other contexts they fit under the definition of non-staple food. All other dairy products—except for fresh butter and ghee when used as tonics (see NP 23)—are non-staple foods. One of the ten disputed points that led to the convening of the Second Council was the issue of whether thin sour milk—milk that has passed the state of being milk but not yet arrived at the state of being buttermilk—would count inside or outside the general category of staple/non-staple food under Pc 35. The decision of the Council was that it was inside the category, and thus a bhikkhu who has turned down an offer of further food would commit the offense under that rule if he later in the morning consumed thin sour milk that was not left over.
I searched for the English translation of that sutta but I couldn't find one. Can someone who is able to read Pali check if that is true and explain to me these apparently opposing guidelines? Vinaya says "Not allowed", Dhamma says "Allowed"!?
Does someone have an English translation of that sutta? Does someone have access to the Pali Text Society English Pali Canon?
Attached a photograph of the respective sutta in thai.
