Below are the only two known references to the Law of Affinity by Alice A. Bailey (AAB) in her voluminous writings and those given to her by 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 a “law” please see Alice A. Bailey – What is a Law?
As we have studied these various constellations, it will have become apparent to you that the main function of the planets is to be distributing agents for the energies emanating from the zodiac as they converge within our solar system and become attracted to our planet. Students need to understand more thoroughly than they do that the basis of the astrological sciences is the emanation, transmission and reception of energies and their transmutation into forces by the receiving entity. The energies of the various signs are attracted by the different planets according to their stage of development and by what is esoterically called “ancient relationship” between the informing entities of the planets and of the constellations. This relation exists between beings and is founded on a Law of Affinity. It is this law of affinity which produces the magnetic pull and the dynamic response between constellations and planets within the solar system and between some particular planet and the forms of life upon another planet and the “impending energies,” as they are called, which are being received from some major source.
You are welcome to post your comments and understanding of this law.
