I think we agree that sometimes people have used and still use numbers for communicating with the gods. But when I balance my check book, I only use numbers to count how much money I have left. I would say that I am in the majority.
I think the same could be said for yoga. Some have probably used it for communicating with the gods. But the majority use it only to keep their joints supple.
It turns out that numbers and yoga are both rather mundane subjects.
It all about context really and what lies in the heart. One stumbles upon a kid doing some yoga moves he learned from his gym teacher, probably not a lot of harm there, he’ probably just stretching as one poster put it! Doing yoga and incorporating TM or hindu/bhuddist chants, quite another issue again, which the pastor mentioned in the posting was trying to warn against.
Similarly with math, it helps me with my checkbook as well though I often fret as to how little my account contains after expenses and all the freaking taxes we have to pay!
