Throughout the Gemara there are many stories in which Eliyahu HaNavi appears in one form or another and is in conversation with Chazal.
Have any commentators or scholars provided a systematic approach to understanding these episodes and what it is Eliyahu HaNavi could represent in these stories or is it to be understood like all Divre Aggada?
(I'm looking for a comprehensive approach but I'll cite a few examples that come to mind, although I'm sure there are far more well known stories than these: Gittin 6b, Taanit 22a, Berakhot 3a, Sanhedrin 98a)
