We will be touching on this later but i felt it is good to post a little bit here, as there are so many distinctions and information about Guardian Angels it can be over whelming, and not many know of the Guardian Wall. From the Theosophical Glossary
Guardian Angel Christian term for the various classes of dhyanis which guard the worlds, races, nations, and mankind pertaining to them. The five middle human principles are the essence of the sixfold dhyani-chohans and of the pitris. Equivalents are daimones, genii, theoi, devas, gods, Paracelsus' flagae, etc. The personal quality that pervades so much of Christianity represents them as special to each individual, which is true enough in a sense; and they may be anything from a ray of divine light from the core of our being, to the kind of karmic heirloom designated as one's lucky star. As a matter of fact, there is for each human individual an ever watching, forever guiding and stimulating spiritual power within himself, his own spiritual ego which, when allowed by the brain-mind, infills the individual with its strength, wisdom, and peace.
Guardian Wall A collective or generalized title given to the body of nirmanakayas and their immediate chelas or disciples who watch over, protect, and help humanity and all creatures of earth, each initiate being compared to a stone in the Guardian Wall (VS 68).
