Rav Meri said that one can infer from the Mishna that those who treat their non-sacred items as if they are sacrificial meat, the laws of sacrificial meat actually apply to them. From where in the Mishna is this inferred? A number of laws are brought regarding one who has a lapse of thought in protecting an item from impurity and the item is therefore not considered protected and is treated as impure. Some of the cases are where one confuses one item for another. Is that really a case where we say there was a lapse of thought? In a braita, a case is brought where one confuses wine with oil and yet it is still considered pure! Before the Gemara answers the question, they ask a counter-question - why does the braita forbid one to eat the oil? Rabbi Yirmia answers that the case is one where it was watched from becoming impure in a way that it would pass on impurity (contact with a first or second-degree impurity - because of the stringency of the rabbi regarding liquids) but not from becoming disqualified/impure (contact with a t'vul yom). Is there really such a thing as watching an item partially? Yes, and a braita is brought to prove that. The Gemara goes back to the question about why a lapse of thought would cause an item to be impure and raises more questions from sources that indicate that if one intends to watch an item, it is considered protected from impurity. In the end, answers are brought to explain why these situations were unique. The Mishna lists many issues for which sacrificial meat is treated more severely than teruma.
