and after COVID hysteria
In the sefer Chafetz Chaim al HaTorah [Va’eschanan] the Chafetz Chaim explains why the posuk of “vi’nishmartem meod l’nafshoseichem”, which includes the commandment to guard one’s health, uses the term of nefesh, rather than the term guf. He explains that while engaging in the process of guarding the physical health, one may not thereby trample on his spiritual health.
