The Prohibition Against Self-Injury
Jewish law forbids inflicting bodily harm upon oneself, even with personal consent, grounded in the Torah's command to guard one's life and body.

Automated Processes Running on Shabbat

Pikuach Nefesh and Non-Kosher Organ Transplants
These sources address whether the prohibition against consuming non-kosher food is overridden when a non-kosher organ transplant is necessary to save a life. The sources establish the principle of Pikuach Nefesh — that nearly all Torah prohibitions yield to the imperative to preserve human life — and examine whether this principle applies to organ transplantation, which is not an act of eating in the conventional sense.

Business Transactions with Churches in Halacha
Jewish law prohibits certain business dealings with non-Jewish religious institutions, particularly around their festivals, out of concern that profits will support their worship.

Sources explore the halachic permissibility of commercial transactions with churches and other houses of worship, drawing on the biblical prohibition of lo techanem (not granting free favor to idolaters) and its Talmudic interpretation. The discussion examines when such transactions are forbidden, permitted, and how prior acquaintance affects the application of these rules.
