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.
My life, when I look back, has not been easy. One thing I learned was that compassion, a sense of caring, thinking about others' welfare, that sort of mental attitude brings me inner peace.
