Spiritual Awakening, Realization, Enlightenment, Liberation... the name just depends on what your spiritual tradition might be.
Maybe it is better to call it waking up to what is already so and has been so all along.
This is beyond religion.  We are simply finding again who we are--what Mother Nature has known all along and is telling us in the flowers, in the birdsong, in the circumstances of our down-to earth lives and everywhere we look.
