sort of, it's about experiencing all of your feelings and thoughts without attempting to change/ignore them, which can be quite hard to do, as we all attempt to change/ignore things, especially if they feel uncomfortable, which is why support/a teacher is helpful. this doesn't mean you do accept everything or do not change anything, but when you come from a place of not avoiding or indulging etc, your response may (or may not!) be different, because you are clearer about what actions to take, or not to take. all the mindfulness and meditation practices available to us now, come from ancient eastern teachings, and are a way of making these teachings accessible to us western folk. It has helped
me sometimes, but I find it v difficult to do, especially on my own. but any practicing is good!
