Jelena Girlin's debut-film – graduation film of the Academy of Art.

Question: "What is the guff?"

Answer: The guff is a term the Talmud uses to refer to the repository of all unborn souls. /---/

Literally, the word guff means "body." The Talmud essentially says, "The Messiah will not arrive until there are no more souls in the guff.” The Talmud is saying that there are a certain number of souls in heaven waiting to be born. Until they are born, they wait in a heavenly repository called "the guff," and the Messiah will not arrive until every single one of these souls has been born into the physical world.
