Can an atheist practice Yoga? Is there enlightenment without God?
There is enlightenment both with and without God. This is because human beings are inherently enlightenable, transformable to a higher state of evolution, regardless of the belief system utilized. We could say that all of existence is headed in that direction, from the rocks up through all the kingdoms of living things. Everything is moving forward. Humanity is no exception. We humans have an added ability to consciously accelerate the process, to choose a fast track, which is what advanced yoga practices are about. We can turbo-charge the evolutionary process.
