Magic Forums

So,I'm technically a beginner to magick and spell casting, but numerous times on this site ,more experienced members have mentioned that its generally impossible to make transformations to your body and likewise due to the limitations of nature that we have on the physical plane. But, I was reading about the work done by a Dr. Joe Dispenza, where he showcases that thoughts can affect and make the body undergo transformations. Also , thoughts basically are just a form of intent, which we usually use to fuel our magick spells, so does't that mean that with thoughts and therefore, intent , we can alter our bodies to some degree or have I possibly misunderstood something?
