This is Balaji from chicago.A quick hi to everyone.I am quite baffled by the science of yoga.A friend of mine introduced me (rather forced me… :P) to a workshop called Inner Engineering offered by Isha foundation in chicago.They taught me this kriya called shambavi maha mudra.I was irregular initially ,but now that i have seen it work ,I do it regular and it takes only 20 minutes.It somehow gives me a lot more energy and I had an awesome summer.I would work from 6 to 3 and play from 5 to 10 pm.
I am eager to share what I know and learn from others here.I am not qualified myself to be teacher ,but can guide to the right place 
err…made a typo in the title.don’t know how to fix it.
