As noted in the above paragraph, there are secondly three Entities Who embody planetary principles. They are (speaking from the present standpoint) the dynamic energy which holds together the three lower kingdoms, viewing these kingdoms as units and not as differentiations. They are closely connected with the energy aspect of the three earlier chains, and it only needed the work of an interplanetary avatar (at the formation of the triangle which resulted in the individualization period in Lemurian days) to enable Them to take etheric bodies and incarnate among men. They act as focal points for the energy of the planetary Logos on His own plane. The first Kumara is in a mysterious sense the energy which produces self-consciousness in the human family. The three other kumaras, or the three Buddhas of Activity, act as similar focal points for the energy which animates the three lower kingdoms, and which produces their differing grades of consciousness. It is not possible to express this great mystery more clearly but if the student couples these few hints with those earlier given in the Secret Doctrine, the mystery of the "Holy Four" may be somewhat clarified from the standpoint of energy and evolution.
