Well yes and no. If my mind is constantly jumping from on thing to the next then how can I meditate? We ground ourselves with our physical senses such as breathing and focus on what we are focusing on. Be it healing or Serenity or nothing.
I think its important to be nonjudgmental during meditation. I simply observe the thoughts and let them go. If I “try” to stop them I’m giving them my energy and feeding into the trap of the egoic mind. If I just observe them it’s like pitting a flashlight on a shadow. They may come up… a lot!! Lol especially with addiction, but mindfulness is like mental jujitsu when were smothered we make space. Space is done by equanimity based observation.
Another way to think about it is redirecting the chattering of the mind to the now. Right now is real, everything else in the past or future is not real and largely a waste of energy. Like having 80 windows open on your pc when you only need one. So grounding your mind through breathing, walking, listening, feeling, seeing ect places you in reality.
Just kinda how I see it, but i suck at meditation lol… I’m like the worst Buddhist ever
