To study angels is to shed light on ourselves, especially those aspects of ourselves that have been put down in our secularized civilizations, our secularized educational systems, and even our secularized worship system. By secularization, I mean anything that sucks the awe out of things.
Faith is strong trust in self and life even in the face of evidence to the contrary. Like belief, it consists more in love than knowledge, or perhaps it is just that love takes precedence. It is intuitive. It is a power of the soul, not of the mind alone and based on the most subtle of perception. It is born and nurtured in the area of the third eye, the open heart, and the sensitivity of an ear tuned to mystery.
