According to Cohen and Wilber, "enlightenment" does not refer to an unchanging state, but has to be in accord with an ongoing evolution of humanity, which is the "Authentic Self." According to Cohen, individuals need to recognize that their own spiritual transformation is essential for cultural evolution. To achieve that, in Cohen's view, an individual should strive to realize his or her true self as being "one with the timeless Ground of all Being and with the evolutionary impulse that is driving the entire cosmos."
