Can anyone explain to me what a "Spiritual Awakening" is? What does it feel like? Has anyone ever experienced it?
The term you are using -- "spiritual awakening" -- strikes me as Christian. In Christianity, the term seems to most commonly refers to an emotional and heart felt commitment to faith in God or Jesus. Or faith that they might save one.
I have noticed, however, that in recent years a few Christians have used the term for what is more traditionally called a "religious experience". That is an experience of God such as -- but not necessarily limited to -- hearing God speak, seeing a vision of Jesus, feeling the Holy Spirit moving powerfully within them, etc.
Religious experiences are to be distinguished from "mystical experiences". A religious experience is an experience of a specific, identifiable deity. A mystical experience transcends any and all religions -- the "deity" of a mystical experience is not specific to any religion.
In fact, the deity of a mystical experience might not even be a deity in any normal or usual sense of the term. We know so very little about it, although the science of mysticism has made leaps and bounds in the past 20 or so years as new brain imaging techniques have come online -- and as comparative religious studies have developed and applied new methods of analysis. Still, it remains a mystery and -- I think -- it always will in some ways.
By the way, where did you hear the term "spiritual awakening"? What was the context? And why does the concept interest you? Please answer only if you feel comfortable doing so.
