Found this from The AV Club, it further explores Buddhism in Groundhog Day from a previous post I had made:
(also explores the many deep concepts that Bill Murray's characters have touched on)
The Buddhism of Groundhog Day
Though everyone from secular self-help therapists to Catholics have claimed it as their own, Groundhog Day is especially beloved by the Buddhists, who view it as an illustration of the notion of “samsara”—the endless cycle of birth and rebirth that can only be escaped when one achieves total enlightenment. In the film, Murray’s sarcastic, self-serving weatherman is forced to repeat a single day out of his life until he comes to terms with the Four Noble Truths: 1) Life is suffering (but that doesn’t mean you have to add to it by being a jerk). 2) The origin of suffering is attachment to desire (so don’t spend your days robbing banks, stuffing your face with danishes, and trying to bamboozle your way into Andie MacDowell’s pants). 3) There is a way out (by dedicating your time to bettering yourself), and 4) it involves following the “eightfold path,” which means revoking self-indulgence and becoming a “bodhisattva”—someone who acquires skills and uses them in the selfless service of others (like changing an old lady’s tire, saving kids who fall out of trees, and performing the Heimlich maneuver on a choking victim). As a result of Murray’s generous acts, he receives the love of the whole town—a oneness with the universe—and is allowed to evolve past the cycle of samsara to nirvana. In this case, “nirvana” means renting a house in rural Pennsylvania and waking up next to Andie MacDowell every day, but hey, whatever makes him happy.
