Mentioned a suggested reading in the text of Alcoholics Anonymous "The Big Book" as a source to learn the various forms a spiritual awakening might come about or manifest itself.

From Page 28:
  The distinguished American psychologist, William James, in his book "Varieties of Religious Experience," indicates a multitude of ways in which men have discovered God. We have no desire to convince anyone that there is only one way by which faith can be acquired.

From Spiritual Experience:
  Among our rapidly growing membership of thousands of alcoholics such transformations, though frequent, are by no means the rule. Most of our experiences are what the psychologist William James calls the "educational variety" because they develop slowly over a period of time.

   A book by the Harvard psychologist and philosopher William James that comprises his edited Gifford Lectures on "Natural Theology" delivered at the University of Edinburgh in Scotland between 1901 and 1902.

   Scientific theories are organically conditioned just as much as religious emotions are; and if we only knew the facts intimately enough, we should doubtless see 'the liver' determining the dicta of the sturdy atheist as decisively as it does those of the Methodist under conviction anxious about his soul. When it alters in one way the blood that percolates it, we get the Methodist, when in another way, we get the atheist form of mind.

   These lectures concerned the nature of religion and the neglect of science, in James' view, in the academic study of religion. Soon after its publication, the book found its way into the canon of psychology and philosophy, and has remained in print for over a century. James would go on to develop his philosophy of pragmatism, and there are already many overlapping ideas in Varieties and his 1907 book, "Pragmatism."
