List the religion that Morrie used for his beliefs

Morrie called himself a religious mutt, meaning he borrowed from different beliefs. He often borrowed from Christianity, Judaism, and Buddhism. Morrie says that if you prepare yourself for death, you can be more involved in your life. This is a Buddhist tactic, ask yourself if today is the day and if you died today, would you have been who you wanted to be and done all you wanted to do? He says learning to die is learning to live.
