Parah 11:5 - 11:6

כל הטעון ביאת מים מדברי סופרים – as for example, that he ate impure foods and drank impure liquids, and the hands and vessels that were defiled by liquids and similar things (see also Tractate Zavim, Chapter 5, Mishnah 12).

וחכמים אוסרים במעשר – and the Halakha is according to the Sages.

לאחר ביאתו – after he ritually immersed, immediately he is permitted to all of them and does not need [the arrival] of sunset.

ואם בא אל המקדש פטור – for the Torah did not forbid his coming into the Sanctuary other than on someone who was defiled by a primary source of ritual uncleanness according to the [Written] Torah, as it is written (Leviticus 5:2-3): “[Or when a person touches any impure thing – be it the carcass of impure beast] or the carcass of impure cattle or the carcass of an impure creeping thing [- and the fact has escaped him, and then being impure, he realizes his guilt;] Or when he touches human impurity [-any such impure whereby one becomes impure – and, though he has known it, the fact has escaped him, but later he realizes his guilt].”

מטמא את מי חטאת – and even after he ritually immersed, [but] if he didn’t ritually immerse for the purpose of the purification rite it is as if he did not ritually immerse, as is taught in the [second] chapter [of Tractate Hagigah folio 18b/Chapter 2, Mishnah 6]: "אין דורשין"/They do not expound [upon the laws of prohibited relationships]: “[If] he immersed for eating food in the status of Holy Things and is thereby confirmed as suitable for eating food in the status of Holy Things, he is prohibited from engaging in the preparation of purification water.” But once he ritually immersed for the sake of the purification water, even a person who ritually immersed himself that day, according to the Torah, who is invalid for heave-offering and for Holy Things, is fit/appropriate for the purification water, for a person who ritually immersed himself that day/טבול יום is fit for the [ritual of the Red] Heifer.

ומזה מי חטאת במגע ובמשא (the one who sprinkles the purification water in contact and carrying) – and in this, everyone does not disagree. But regarding hyssop that is pronounced fit to receive ritual defilement, and because the person who eats them he requires being made fit that [purification] water can come upon him, and similarly, with water that is not mixed [with ashes] and stands for Holy Things, and an empty vessel that is clean and stands in order to place in it the purification ashes, but in this, Rabbi Meir (i.e., contact and carrying) and the Sages (i.e., in contact, but not in carrying) dispute (i.e., if he carried them but did come in contact with them, they are not defiled). And the Halakha is according to the Sages.
