Today’s world is populated. Isolated places are few. Man is a social animal, as is already known. For traditional Yoga goals, an isolation is recommended, but mostly unavailable. Also, world is poorer today than what we think. One has to work several hours a day, mostly as a good looking slave, just to make living. Isolated Yoga practice needs a different environment. What to do in such a situation?
It is best to find a company of like minded and practice together. Try to spend time in this company as much as possible. And, make your Yoga practice stronger as much as possible. In the meantime, try to come out of the slavery of profession, slavery of job, and such by using skillful ways. Save money, reduce needs, reduce expenses, educate yourselves, etc.
Once you are strong, you can create Isolation wherever you are. Best wishes.
