The only known references to the Law of Causes 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.

Four things meditation does:
l—It enables a man to contact the Ego and to align the three lower bodies.
2—It puts a man into an attitude of equilibrium, neither utterly receptive and negative, nor utterly positive, but at the point of balance. Thus is afforded opportunity to the Ego, and later to the Master, to disturb that equilibrium and tune the quiescent vibration to a higher note than heretofore; to cause the consciousness to vibrate to a newer and higher measure, and to swing (if so I may express it) into the periphery of the threefold Spirit. By the constant practice of this, the whole point of equilibrium is gradually shifted higher and higher, until the time comes when the lower point of attraction in the swinging and adjustment, is not the physical, touches not the emotional, contacts not the mental (the causal body even escaping) and the man is polarised in the spiritual consciousness from thenceforth.
This marks the fourth Initiation; after that Initiation, the Adept makes for Himself a body of manifestation, a free creation,—there is nothing in Him to call into objectivity a body for use in the three worlds and evolved under the Law of Causes.
