Below is the only reference to the Law of Passive Resistance in the writings of Alice A. Bailey (AAB) and Djwhal Khul (DK). Links on these pages of the Laws of Alice A. Bailey are to the online books at the Lucis Trust website.
For a discussion of what AAB means by “law” please see Alice A. Bailey – What is a Law?
This Law of the Schools does not specifically apply to the deva evolution. They come under another law called “The Law of Passive Resistance” which does not concern us here, nor would it profit us to consider it. Three main groups of existences are controlled by it:
1. Human beings from the moment they tread the Probationary Path.
2. All the units of the fifth kingdom, therefore, all the members of the Hierarchy.
3. The planetary Logoi throughout the system.
Writing on “deva evolution“:
“This is a mystery which will be solved as man arrives at the consciousness of his own solar Angel, only to discover that that too is also but a form of life which, having served its purpose, must be left behind. The angel or deva evolution is one of the great lines of force, contained in the divine expression and the solar Angels, the Agnishvattas of The Secret Doctrine and of A Treatise on Cosmic Fire belong—in their form aspect—to this line. Thus humanity serves, and in the development of a conscious aptitude for service, in the growth of a conscious understanding of the individual part to be played in the working out of the plan and in the rendering of the personality subject to the soul, will come the steady progress of humanity towards its goal of world service.” -A Treatise on White Magic
