Following the previous question:
The Gemmorah BM 85a:
"ר' זירא כי סליק לארעא דישראל יתיב מאה תעניתא
דלשתכח גמרא בבלאה מיניה כי היכי דלא נטרדיה"
"When Rabbi Zeira ascended from Babylonia to Eretz Yisrael, he fasted one hundred fasts so that he would forget the Babylonian Gemara, so that it would not hinder him from adapting to the unique style of study prevalent in Eretz Yisrael. "
What part of his Babylonian memories did he mean to forget: all the arguments, the methods, the resolutions, the decrees?
Also we currently hold the Babylonian Talmud as the final, complete and Halachic one. Why would he want to forget any of this?
