Ah, "heat."

I have been told about "heat." When I was in India I wore my hair tightly pulled back in a bun because a woman's unbound hair radiates "heat," a sensual energy that can turn destructive until unbridled feminine energy runs amok like Kali through the countryside. I didn't want people looking at me and worrying that I was going to go on a rampage and ruin all their lives and swallow their rickshaws whole, so I just put my hair away, lest people fear that my rampaging shakti energy would escape without a man holding my leash and channeling my terrible destructive power.

I don't buy the metaphysical notion of "heat" at all, frankly. The idea that chanting certain words channels the cosmic energy down into an ascetic, potentially fueling formidable magical powers that could cause a sadhu to become a threat even to the gods themselves is an idea from Hinduism that I've chosen not to allow to contaminate my dharma practice. If it unsettles you or fails to make any sense at all, then I'd say ignore it. It will certainly not cause you reproductive problems any more than blowing a didgeridoo will make you sterile. It's just superstitious nonsense, intended to keep women from doing certain things that were considered inappropriate or culturally unacceptable for our sex.

Seriously, every time somebody doesn't want women participating in something, they say, "It'll make you sterile and no man will ever want you if you're sterile, so watch out! Put down the didgeridoo!"
