You start off by saying that only hard work can bring about bliss, and when confronted with a different experience you pigeonhole it into asserting that bliss must befall every single person regardless of their circumstances. Step aside from the false dichotomy - it's not the case that yoga can either bring about bliss quickly to everyone or no one. It may bring to some and not to others. Will it work for a particular person? The easiest way to find out is to try. There is no point in guessing. Sign up for 8-class introductory course, by the end of it you will have a pretty good idea whether it works for you. It worked for me, and it worked for other people I know, so it works for some people. It's not going to be a waste of time. If you're worried about prerequisite fitness level, I can guarantee you that I had the worst stretching and the least endurance of the entire group - it's fairly obvious in class. One thing I had more that others is discipline - I think I was one of the few to attend all eight classes.
