Below is the only known reference to the Law of Triple Response 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 a “law” please see Alice A. Bailey – What is a Law?
But—and this is a point I seek to impress upon you—humanity, subjected to this constant process of expansion from the emergence of the fourth kingdom in nature, the human, has now reached the stage where it can begin to pass out of the control of what has been called the Law of Triple Response into a new phase of unfoldment where a recognised dualism dominates. This is a most important statement. Let me word it in this way and let me commend to you a very careful consideration of my words. I will express what I seek to impart in certain short sentences and in tabulation form:
1. The advanced man in the three worlds is conscious of two inherent triplicities:
a. The lower man – Physical body – Astral nature – Mind.
b. The three periodical vehicles – Monad – Soul – Personality.
2. Soul and personality have made contact. He is now technically soul-infused. Two periodical vehicles have been at-oned. Three lower vehicles and the soul are united.
3. The etheric body is at the point of assuming great power. It can now be consciously used as a transmitter of:
a. Energy and forces, consciously directed.
b. Impacts from the highest of the periodical vehicles, working through its instrument, the Spiritual Triad.
4. The etheric body is, therefore, the agent consciously directed, of the rapidly integrating spiritual unity. It can convey into the brain the needed energies and that occult information which together make a man a Master of the Wisdom and eventually a Christ – all-inclusive in His developed attractive and magnetic power.
