(Beraisa): A sick Ba'al Keri that nine Kabim of water fell on him, he is Tahor for himself, but he cannot be Motzi the Rabim until he comes in [a Mikveh of] 40 Sa'im;

R. Yehudah says, 40 Sa'im in any case [even Mayim She'uvim, or even in a Kli, even though it is not a Kosher Mikveh].

(R. Yakov bar Acha citing R. Yosa citing R. Yehoshua ben Levi): [The Isur of Divrei Kedushah for a Ba'al] Keri is only from Bi'ah;

(Rav Huna): It is even [due to an emission that came due to] seeing himself [having Bi'ah] in a dream.

Assumption: They wanted to say that it is only [if he saw himself having Bi'ah] with a woman.

Rejection (R. Yonah and R. Yosi): It is even [if he saw himself having Bi'ah] with something else (a male or animal - CHAREDIM).

Question: A Mishnah teaches that on Yom Kipur it is forbidden to eat, drink, bathe, anoint, wear shoes or have Bi'ah, and a Beraisa taught that a Ba'al Keri immerses normally, in private, on Yom Kipur;

Does this not argue with R. Yehoshua ben Levi? R. Yehoshua ben Levi said that Keri is only from Bi'ah!

Answer: He explains that it discusses one who had Bi'ah during the day (on Erev Yom Kipur), and forgot and did not immerse [before night].

Question (Beraisa): A case occurred in which R. Yosi ben Chalafta, they saw him immerse in private on Yom Kipur.

Can you say that that Kadosh body forgot?!

(R. Yakov bar Avin): The whole reason why they enacted Tevilah [for a Ba'al Keri] is lest Yisrael be like these roosters - it has Bi'ah [very frequently], ascends, descends and eats.

R. Chanina would pass by the gates where people immerse, before dawn, and said 'what are people who immerse in the morning [before learning] doing here'? (It is dangerous at night, like it says below.) They should go and learn!

[Later] in the morning, he would say 'one who has an action (he had Bi'ah), he should go do (immerse).' (We explained this like MAHARA FULDA.)

Question: May one think [about Torah] in the privy?

Answer: Chizkiyah permitted, and R. Yosa forbade.

R. Zeira: Any hard matter [that I pondered], I resolved it there (in the privy).

R. Elazar b'Ribi Shimon: The entire difficult deliberation about a Tevul Yom (whether or not he is entitled to receive a share of Kodshim, in order to eat it at night, when he will be fully Tahor - Zevachim 102b), I reasoned it there.

(R. Acha citing R. Tanchum bar Chiya): In the days of R. Yehoshua ben Levi, they wanted to uproot this Tevilah, due to women of Galil, who were becoming sterile due to the cold (their husbands refrained from relations due to the difficulty of immersing);

R. Yehoshua ben Levi: Something that fences Yisrael from Aveirah - do you seek to uproot it?!

Question: How does it fence Yisrael from Aveirah?

Answer: A case occurred with a watchman of a vineyard who wanted to have Bi'ah with a married woman. While they were preparing a place where they will immerse [afterwards], people passed by, and the Aveirah was canceled.

A case occurred with one who wanted to have Bi'ah with Rebbi's Shifchah. She told him, if my mistress does not immerse, I do not immerse (lest it be clear that I was Mezanah. The decree of a Ba'al Keri applies also to women who emit semen.)

The man: Are you (slaves) not like animals?! (Are you concerned for this decree?! We explained this like CHOMAS YERUSHALAYIM.)

The Shifchah: Did you not hear that one who had Bi'ah with an animal is stoned - "Kol Shochev Im Behemah Mos Yumas"! (It seems that this was the same Shifchah from whom Rabanan learned several matters (Megilah 18a), and honored her Cherem for three years (Mo'ed Katan 17a). In any case she would not consent to Zenus, just she gave an excuse that the man who desired her would accept - PF.)

(R. Chiya bar Vah): The whole reason why they enacted this Tevilah is only due to Talmud. If you will say that he is permitted [to learn before immersing], he will say 'I will go, do my needs (Bi'ah, so I can learn without Hirhur - MAHARA FULDA), and learn';

Amidst that you say that [a Ba'al Keri] is forbidden [to learn before immersing], he will learn as much as he needs [before having Bi'ah. We explained this like R. SHLOMO SIRILIYO.]

There (in Bavel) they say that even to hear Divrei Torah is forbidden [before immersing].

Source (R. Yehudah bar Titam citing R. Acha citing R. Elazar): This is like the beginning (when Yisrael merely heard Torah on Sinai) - "Heyu Nechonim li'Sheloshes Yamim Al Tigshu El Ishah" (they separated for three days, for until then a woman can emit semen from Bi'ah).

(Beraisa): Zavim, Zavos, Nidos and Yoldos may recite Torah and learn [Halachic] Midrash, Halachos (Mishnayos) and Agados. All of these are forbidden to a Ba'al Keri .

(R. Aba bar Acha citing Rebbi): He may learn Halachos, but not Agados.

(Beraisa - in the name of R. Yosi): He may learn Halachos that he is fluent in them (and need not investigate them), as long as he does not give reasons for the Mishnah (R. SHLOMO SIRILIYO).

Some want to say, as long as he does not mention Azkaros (names of Hash-m).

Question (R. Ze'ira, to R. Yosa): Does not Rebbi (you) learn with R. Bun [at the end of every] night (even if one of you had Bi'ah, before immersing - CHAREDIM)?

Answer (R. Yosa): Yes! R. Chiya bar Aba learns with his son R. Nechemyah at night (after Bi'ah), and in the morning, he would say 'one who has an action [to do, i.e. to immerse from Keri], he should go do.' (We explained like MAHARA FULDA, with a small change.)

A case occurred with [a Ba'al Keri] who stood to recite Torah in Netzivin. Once he reached an Azkarah, he stuttered. R. Yehudah ben Beseira told him "open your mouth and let your words illuminate. Divrei Torah do not receive Tum'ah!"

(R. Yakov bar Acha): People there (in Bavel) conduct themselves like R. Ila'i regarding Reishis ha'Gez (giving first shearings to a Kohen), like R. Yoshiyah regarding Kil'ai ha'Kerem, and like R. Yehudah ben Beseira regarding a Ba'al Keri (these will be explained);

They follow R. Ila'i regarding Reishis ha'Gez.

(Beraisa - R. Ila'i): Reishis ha'Gez applies only in Eretz [Yisrael].

They follow R. Yoshiyah regarding Kil'ayim;

(Beraisa - R. Yoshiyah): One is liable [for Kil'ai ha'Kerem] only if he seeds wheat, barley and a grape seed together.

They follow R. Yehudah ben Beseira regarding a Ba'al Keri;

(Beraisa - R. Yehudah [ben Beseira]): Divrei Torah do not receive Tum'ah.

R. Yosi ben Chalafta was going in the dark (MAHARA FULDA) at night. A donkey-driver was in back of him. They came to a pit [of water]. The donkey-driver said that he needs to immerse. R. Yosi told him, do not endanger yourself [to immerse at night].

The donkey-driver said, I need to [immerse, to] purify myself from Bi'ah with a Nidah and with a married woman! R. Yosi told him, do not endanger yourself.

Since he did not heed him, [R. Yosi] said, he should descend [into the water] and not rise. And so occurred to him.

R. Yosi ben Yosi was coming on a boat. He saw a man tie himself with a rope in order to immerse (and they will pull him back to the boat). R. Yosi told him, do not endanger yourself.

The man said, I want to eat (and I must immerse in order to bless before eating)! R. Yosi told him, eat (you may bless without immersing). The man said, I want to drink! R. Yosi told him, drink.

Once they reached the port, [R. Yosi] told him, there, I permitted you [to eat and drink without immersing] only due to mortal danger. However, here that man (i.e. you) may not taste anything until immersing.

(R. Yanai): I heard that some are lenient about it, and some are stringent. Anyone who is stringent will have length of days and live well;

Some are lenient to bathe in Mayim She'uvim (it is not a real Tevilah). Some are stringent to immerse [a proper Tevilah] in Mayim Chayim (a spring, or in a Mikveh).
