375 – 79: “THE FUNCTIONING RAY LAWS. There are certain great laws, connected with the seven rays that are effective in determining the lines of demarcation, the cleavages which produce separation and the differentiations of the manifested life of God into…

1. The septenary constitution of the solar system.
2. The ten schemes which indicate solar achievement.
3. The inner constitution, or so-called “chains”, which distinguish each planetary existence.
4. The planetary constitution of our Earth into the various kingdoms of nature.
5. The basic distinctions between the kingdoms; these produce the types, groupings, families, branches, empires and nations.

“These Laws of Cleavage are too difficult for general comprehension.  They govern form life, and are the result of the united working, or rather the simultaneous manifestation, of the three laws dealt with in A Treatise on Cosmic Fire. These are:

1. The Law of Synthesis, determining the future, certifying the goal, and concerned with the life or spirit aspect.
2. The Law of Attraction, determining the present, and governing the immediate condition of the planetary types. It is concerned with the consciousness or the soul aspect.
3. The Law of Economy. This law determines the past, conditions the planetary consciousness, and concerns itself with the form or matter aspect.”

When these three function together, during this particular cycle and in our particular race, they produce a fusion of forces which imposes a certain rhythm, a definite materialisation of energies, and a specific type of civilisation which functions under what we (esoterically) call the Laws of Cleavage.  It is the mind which separates and divides; it is mental activity (divine and superhuman, as well as human) which produces the many differentiations.  This process of divisioning comes to its climax during this world period in the Aryan race, the fifth race.  We are today governed by the Law of Cleavages, – a divine law and one of fruitful objective.”

379: “Let us now enumerate these laws in sequence, so as to gain a better idea of their relation and interrelationship:

1. The Law of Immersion – First race
2. The Law of Capitulation – Second race
3. The Law of Materialisation / of Hidden Radiance – Lemurian race
4. The Law of Tides – Atlantean race
5. The Law of Cleavages – Aryan race
6. The Law of Loving Understanding – Next race
