The term is piqua nevish [?] it means to save a soul, to save a life. And that commandment supersedes all others. It means literally you may violate almost everything except, I think, three commandments of the heart, 613, - you may do anything, violate any commandment and the injunction simply to save a human life. And there are enough lives to be saved in - in Tibet.
