There is a little known Chassidic text published in 1834 entitled Pri Yitzchak that details all 613 Mitzvot and the corresponding limbs for positive mitzvot and 365 Gidim for negative commandments. It has not been translated from the Hebrew. It is a very sophisticated work. He uses the list of halachic limbs listed in the Mishna, and uses the Rambam's list ...

See this comprehensive survey at Aish, about plastic surgery in general. It mentions this kohen reason, in the name of Rabbi Menashe Klein, in his Mishneh Halachos, and (IIUC) Rav Shlomo Zalman Aurbach. But others permit for very different reasons: Thus: In 1961, Rabbi Immanuel Jakobovits, considered by many to be the father of the discipline of Jewish ...

The Tzitz Eliezer has a famous responsum (שו"ת ציץ אליעזר ח"י סי’ כ"ה פרק כ"ו קטע ו) where he states that we go by the external organs in determining gender, and sex changes are effective in changing one's halachic gender. However, there are other opinions that sex changes do not change halachic gender; I assume that according to these opinions, gender is ...

Chelev (the word translated as "fat" in the quoted verse) in Halacha refers to certain fats which in a sacrifice are offered on the altar and in regular meat are forbidden to be eaten, while Shuman refers to other fats which are completely permitted. A list of which fats on which body parts are in which category is something which pretty much can only be ...

See Yoreh Deah 362 Pischei Teshuva #1 were it seems amputated organs need not be buried, but consult your LOR (local orthodox Rabbi). Also see Kesuvos 20b where the custom is to bury amputated organs.

after the circumcision, the foreskin is buried (some prepare a dish with dirt in it to "bury" the foreskin immediately). Some bury it in earth that has a new tree planted in it as a symbolic connection but the operative point is respect and burial for the body part. cf Do surgically removed body parts require Kevurah? the comments on the question which ...

The original question as well as @SAH challenge seem to imply that the Torah forbids piercings. This belief is possibly coming from the prohibition of tatoos as the prohibition to injure oneself. But as we will say the halacha doesn't necessarily consider all body piercings forbidden. As context, plastic surgery (a more extreme form of bodily injury for ...

Someone asked this question online to Rabbi Yitzhak ben Yosef (posek and rabbi of Ramat Gan) here, and he responded as follows: בהחלט שאלה נדירה ביותר. לכאורה כל תינוק הוא פטר רחם וצריכים שני הילדים פדיון צריך לבדוק האם הם פטר רחם דהיינו שלכול רחם יש פתח נפרד. This is an extremely rare case. Seemingly, each infant is the"opener of the womb" and ...

The classic Sefer Chareidim by R' Elazar Azikri (d.1600) catalogs all the mitzvos according to body parts. (R' Elazar Azikri was also the author of the poem, Yedid Nefesh.) An abbreviated version, Kitzur Sefer Chareidim, was written by R' Avraham Danzig, author of the Chayei Adam. The sefer does not attempt to establish a precise one-for-one match for each ...

There are many explanations to the significance of creating Eve from Adam's rib. By the way, it's not a universal opinion that "tzela" should be translated as "rib" (Hazal have also transalted it as "side," which works with the midrash of them being originally joined together). Going with the "rib" translation, here are a few explanations. Bereshit Rabbah ...

There are midrashim that speak of Adam and Chava being a single unit before Chava was separated from Adam. The cryptic nature of the pasuk could lead us to think of Adam and Chava as being one (Bereishit 1:27): וַיִּבְרָא אֱלֹהִים אֶת-הָאָדָם בְּצַלְמוֹ, בְּצֶלֶם אֱלֹהִים בָּרָא אֹתוֹ: זָכָר וּנְקֵבָה, בָּרָא אֹתָם. The next statement about separating ...

Biblical mitzvos are in bold. Items that are minhagim or otherwise are not mitzvos are listed for completeness but are not bold. -- Each is followed by the corresponding (set of) body part(s) 30 days of blowing shofar (in Elul) -- 30 in the feet 10 offerings brought on Rosh Hashana -- 10 in the ankles 2 approaches to the aron(?) -- 2 in the shins 5 people ...

Tzitz Eliezer (Vol. 6, Siman 40, Perek 22, Ois 8, and Vol. 7 Siman 46 and Vol. 12 Siman 67) says that it is allowed. However, Rabbi Moshe Feinstein (Iggros Moshe Even HaEzer Vol. 4 Siman 65 Ois 10) says only rabbinic Yichud is allowed, but cases which are forbidden Biblically are not.

Read Igros Moshe Choshen Mishpat 2:65 and 66 who discusses elective surgery and difference between destructive wounds and unharmful wounds.The tshuvah is very lengthy and goes through the gemara,Tosfos and Rambam. At the end of the tshuvah he brings a gemara in Bechoros 45a which brings a case of a person who has an extra finger and then removes it, it is ...

The Talmud (Berakhot 13b) is the original source for this custom. Here there is a mention of Rabbi Judah the Prince covering his eyes while he said the Shema to block out the distractions of the students around him. This behavior was codified in the Shulhan Arukh (OH 61:4-5). from http://www.myjewishlearning.com/ask_the_expert/at/Ask_the_Expert--...

Not sure about sources for most of these (although see Madeleine's comment to the related question). But about the back of the neck, it may be related to the idea that this is the location of the luz bone (specifically, the protrusion where the knot of the head tefillin is placed - Arizal, Likkutei Torah to Judg. 4:5*); it is from this that the body will be ...

Nechpa B'Kesef Vol 2 Even Hoezer 19 says that the prohibition from the Torah is specifically to avoid actual relations, and one who is unable to have relations there is no prohibition. However, he says, it is definitely prohibited M'Drabanan, and it is disgusting and the way of fools.

To answer your question: It's been said in the name of Reb Chaim Kanievsky that one should not hide one's Peyot behind one's ears, but he never says to cut them. There are plenty well respected Rabbis who hide their Peyot behind their ears, and others who have trimmed Peyot . Just to put this in context, let's go back to basics - using classic sources. ...

The ארחות שבת (by Rav Yosef Gelber and Rav Mordechai Rubin) in Vol. 2 on page 294 in Siman 20:154 discusses this. They write that one may wear a retainer - פלטה ליישור שינים - on Shabbat. In the footnotes they explain that since the "medical" action [of moving the teeth] is not apparent, but takes a long time, therefore it's permissible. Same logic should ...

The Gemara (Shabbos 50B) says one should wash his face, hands and legs every day in honor of his Creator. The Mishna Berura (OC 4:2) writes in the name of the Pri Megadim (A"A 4:1) that nowadays since we don't walk barefoot there is no need to wash one's feet (This reasoning is also given by the Noda Biyhudah (OC 2:140)), although the Baal HaTanya (OC 4:21) ...

I don't understand the question. The statement that a person who saves one life, saves the world is an aggadic statement, not a halachic one. Halacha does not allow you to sacrifice one life for the sake of many. If you save a life, that is a great and wonderful thing. If you think you are saving a life, but don't actually do so, it doesn't take away the ...

The majority opinion follows Rabbi Yechezkel ben Yehuda Landau (1713 – 1793) opinion at Noda B’Yehuda I, Yoreh Deah (YD) 90, who holds that the mitzvah to bury separated body parts is required only of people who are dead, because it would be a disgrace not to. Rav Moshe Feinstein (1895-1986), however, held that even the body parts of living people must be ...

A family member was in an accident and there were unidentifiable pieces of flesh and skin preserved in formaldehyde which a rav told us must be buried. so the chevra kadisha did it for us. i dont know about internal organs but I've never heard of burying that.

Tefilin, etc., can be made from animals that die on their own (see e.g. The source in the Talmud is Shabbos 108a). Thus even under a situation where killing animals wasn't possible, leather would still be available.

The reason why we close the eyes of someone who passed away is to show the idea of techiyas hameisim just like when someone sleeps he closes his eyes and when he awakes he opens them so to the dead will reopen their eyes with techiyas hamaisim (nishmas chaim maimer beis perek chof hey) Another reason is brought in lechem haponim siman shin lamed tes We ...

The Encyclopedia of Jewish Prayer: The Ashkenazic and Sephardic Rites (Macy Nulman) has the following on the beating of the heart during Viduy When saying Ashamnu we stand somewhat bent over, without leaning on any kind of support, just as in reciting Modim (MB, 607:10 ; Magen Avraham 607:4), a position of abject humility and contrition.

No, one cannot. Mythbusters determined experimentally that earwax candles are not effective: The skin cells, hair, fatty acids and cholesterol contained in earwax combust quickly and at different rates, which means the icky substance won't stick around long enough to keep the flame on the wick. Given that an earwax candle won't burn, it would not be ...
