"As is well known, the five kingdoms of nature on the evolutionary arc might be defined as follows: the mineral kingdom, the vegetable kingdom, the animal kingdom, the human kingdom, and the spiritual kingdom. All these kingdoms embody some type of consciousness, and it is the work of the Hierarchy to develop these types to perfection through the adjustment of Karma, through the agency of force, and through the providing of right conditions."
