The term "get back to nature" does not mean move out of the city and into the country.
It means get back to one's own nature, or one's own TRUE nature. Which is self-realization. God-union, at-onement. Also called enlightenment, Satori, Nirvana, the kingdom of God, paradise, the garden, Eden, etc.
The country may have less distractions, but one can still find the "GOD WITHIN" in any part of the world.
Nature or creation, is the materialization and manifestation of God (the FIRST COMING) the SECOND COMING or SECOND MATERIALIZATION and MANIFESTATION is through all of humanity.
