The Talmud is an associative work, and this page of Talmud illustrates this. On the page there is an interpretation of the meaning of an expression in the Megillah offered by Rabbi Eleazar in the name of Rabbi Hanina. This prompts the Talmud to offer a whole series of saying by Rabbi Eleazar in the name of Rabbi Hanina. One could look upon that series of sayings as a string of pearls. (I use that metaphor because one of those sayings describes how, when a pearl is lost, it isn’t really lost to itself, for it always remains a pearl; it is lost only to its owner.)
