I don't follow. I can say "well, lympocytes and T-cells exist, but there is no scientific support for the immune system!" But how can you prove that the immune system exists as such? The immune system isn't a "real" thing. Instead, we have created an abstraction by describing the function of a collection of structures and processes and named it the "immune system." Similarly, there is no claim to prove or disprove about chakras. It's just a way to view the function of the body and mind. And, for a very long time, it's been very useful for many people. Your finger-pointing about who does or doesn't believe in "magic" is not pertinent.
