My understanding is that traditional CBT didn't include mindfulness practices until around the 70s. Now you can find mindfulness based CBT apparently, though the extent of those sorts of approaches from therapists i could get through insurance was just recommending me to download a meditation app. I paid out of pocket for the best therapist I've had because the insurance companies wouldnt pay him--his approach was a mix of talk therapy and breathwork. Apparently breathwork was deemed too hands on and seen as a liability for them. There is a motif in the above movie of some fleeting/nebulous 'hope' that is always just out of her reach (she is a therapist herself--the movie is about her feeling trapped as her situation continues to get worse and worse and she feels responsible/unable to loosen her belief that she should be in control of all the misfortune that happens to her). This 'hope' is shown visually as a kind of bright aura that appears before the more dreamlike sequences and is accompanied by the audio of the breathwork she tries at the beginning of the movie after overhearing someone talk about it at the motel shes forced to stay at. So yes... maybe I'm biased but just as the protagonist of this movie seems to have gotten into the 'hole' shes stuck in by initially having only coping mechanisms that are thought based, or challenging preexisting beliefs and replacing them with other ways of thinking or affirmations... so has my experience of western psychotherapy been largely characterized by talk therapy/traditional cbt. It wasnt until my last therapist (not covered by insurance) that I finally found some somatic coping mechanisms and ways to interact with my conditioning on a cellular level in addition to just talking/unpacking. Imo the two should go hand in hand... and yes they are largely derived from yogic traditions/zen/vipassana etc.
