One of the key aspects of any personal development program or indeed spiritual growth is to become self aware, to understand what is going on under the skin, to be sensitive to watch is present in the mind.
And really to increase awareness is to become aware! It’s a practical exercise. All too often people set off on a path of personal development or spiritual growth and they read lots and lots of books, they attend a multitude of seminars BUT they never do anything with the wealth of information they have gathered. As Israel Regardie so accurately puts it in The One Year Manual:
Reading does very little to bring one to any kind of realisation of one’s divine nature.
