Most of the stuff that we consider essential is actually not needed at all. In fact, life would be far better without it. Thus I can imagine a new school of yoga that would teach people how to renounce the superfluous stuff step by tiny step. Here is what to do to get rid of television: sit and stare at a wall, and you will soon see wondrous things. Next, here is what to do to get rid of cooking: marinate your food, and your cooker will be superfluous in no time. Then, here is how to get rid of transportation: walk everywhere, and you will soon find a good job not far from your home. Similar exercises could be devised to get rid of communication by means of electronic devices, healing by means of pharmaceutical products, clothing by means of fashionable gear, and so on. Step by tiny step, people would be taught how to get rid of all the useless stuff. The same school of yoga could also teach people how to find food in the woods, how to keep animals that provide eggs and milk, how to collect and keep potable water, and so forth. And all the steps would be couched in the form of straightforward yoga exercises. Hey, the first tiny step is already behind us!
