Question: What is Kordaikus?

Answer (R. Yosi): It is [the illness called] Hamim.

A case occurred in front of R. Yosi of a weaver, that when they gave to him a red [thread] amidst black [threads], he did his work (as if nothing was wrong). When they gave to him a black amidst red, he did his work. This is Kordaikus that Chachamim said - sometimes he is insane, and sometimes healthy (GRA);

When he is crazy, he is like a lunatic in every way. When he is healthy, he is like a Pike'ach in every way.

A case occurred in front of Shmuel. He said that when he is healthy, he can give a Get.

Question: Does Shmuel hold like Reish Lakish?! Reish Lakish said that [only] when he recovers [we can give his Get, unlike R. Yochanan].

Answer: Shmuel's teaching is greater than Reish Lakish's. [Shmuel] said that when he is healthy (even though he is not fully recovered), he can give a Get] - "v'Sachalimeni v'Hachayeni" (i.e. he is called Chalim (healthy) even before he fully recovered, since now he is healthy - Teshuvas RASHBA 4:201).

(R. Yakov bar Acha): R. Yochanan and Reish Lakish argued about this. R. Yochanan said, when Kordaikus is still upon him, we write a Get and give it to his wife. Reish Lakish said, [only] when he is healed.

Question: Reish Lakish contradicts himself! They argued about one who [was obligated to bring a Chatas for eating Chelev, and he] became a Cheresh or lunatic, or Beis Din ruled (permitted) to eat Chelev;

R. Yochanan said, his Chatas was Nidcheh (rejected. He cannot offer it after he becomes healthy or Beis Din retracts). Reish Lakish said, his Chatas was not Nidcheh.

Answer (R. Yosi bei R. Bun): We must switch R. Yochanan's opinion (with Reish Lakish's), lest R. Yochanan contradict himself;

(R. Shmuel bar Aba citing R. Yochanan): One who is Goses (dangerously ill; most Gosesim die), we throw for him the blood of his Chatas and the blood of his Asham. (A Goses is like a lunatic.)

(Rabanan of Kisarin): R. Chiyah and R. Yosah - one of them said like this (the first version, that R. Yochanan says that his Chatas was Nidcheh), and one of them said like this (like R. Yosi bei R. Bun reversed the opinions).

Question (against Reish Lakish - Mishnah): If one said 'write a Get to my wife', and he was seized by Kordaikus, and he retracted and said 'do not write 'a Get to my wife', his latter words are void. (Reish Lakish says that we cannot write until he is healthy!)

Answer: When he gets healthy, his latter words are void. (We may write without asking him.)
