Yo? You're saying people are able to do Rasengan when they control it? O.o
Of-course not, that's impossible.
The effects of chakra meditation are internal and not physically visible.
Each chakra has it's own benefits and tolls. You are able to see and comprehend the world differently, find your inner truth and much more.
Do further research on the 7 chakras if you're interested.
An honorable mention would be the third eye awakening, again, helps you see the world differently and there are also some supernatural talents that might gift you if you master it.. I watched a video where a girl read with her eyes closed after awakening her third eye. Again, do more research if you're interested.
It's all a large web in the world of spiritualism and chakra meditation is only a sector of it. There are a lot more interesting things to learn about our world and spiritual bodies after death. Astral Projection, the astral planes, our spirit guides etc. It's all down to research. Here's a useful link if you want to learn about life after death:
