I've worked in many sanghas helping set up classes and retreats. It is difficult to learn how to meditate if you don't go to retreat and deeply ingrain the lessons. Also a teacher is needed to help us work our way through all the crap that comes up during meditation. People need to be of sound mind, good health helps too but that isn't as important as a healthy mind.

Why? Because there is some scary shit hiding in the darker corners of our mind. Meditation is like cleaning out the dark corners, cleaning up our house and property. It is hard work and sometimes physically and mentally demanding, even dangerous.

People tend to go for the feel good meditations but I feel that's kind of like masturbating, it's nice but it really only last for a couple minutes and you end up having to masturbate endlessly and sometimes go for extremes to get the same kind of high.

Everyone is trying to be happy but they end up making themselves miserable, this happens with meditation as well.

I can help you find qualified teachers but that won't guarantee that you and the teacher will work well together. It's a tough path to walk but totally worth it from my point of view.
