Yea, I'm conceding the point! I don't think I understood the full connotations and claims to the purpose of chakras. I'd agree with the point made in the thread I linked, that the most reasonable understanding of what they would be in reality is a mnemonic type device for use in meditation, and since effects of meditation are unquantifiable for the most part, it'd be unreasonable to claim that any supposed link between chakras and glands is anything more than a placebo effect.
