According to Ra, at the moment we are born into our incarnation, there are four cycles or rhythms that are set into motion. Three of those cycles are known by various systems as “biorhythms.” There is a fourth cycle that Ra describes as the Adept or Spirit or Gateway of Magic Cycle. (Ra sometimes had multiple names for the same thing.)

As they indicate in the following passages, the Adept Cycle operates on an 18-day rhythm, the 19th day being the first of a new cycle. Where the entity is in this 18-day oscillation can have impact on the entity’s relative power with respect to their ability to conduct a magical working.

Using Ra’s information, the diagram on this page is intended to visualize this cycle with a sinewave over an X-Y graph. The zero point on Day 1 would correspond to the day you were born. From there the 18-day cycle begins and repeats until the end of the incarnation.

Sinewave visualization

Ra reminds the seeker that understanding of this cycle is a helpful tool, but as the seeker becomes more balanced, they are less impacted by the transitions and peaks of the sinewave.

To see a custom-built tool to find out where you are in the Adept Cycle, visit our Adept Cycle calculator. It also includes a map of the biorhythms borrowed from another source, it being one among other possible ways to map the biorhythms. Note that Ra did not explicitly endorse any particular method for defining or calculating the other three rhythms, and they are included on this calculator for sake of novelty.


A compilation of thoughts that Ra offered about the Adept Cycle. See also #61.2, #61.4, #64.11

There are four types of cycles which are those given in the moment of entry into incarnation. There are, in addition, more cosmic and less regularized inpourings which, from time to time, affect a sensitized mind/body/spirit complex. The four rhythms are, to some extent, known among your peoples and are called biorhythms.

There is a fourth cycle which we may call the cycle of gateway of magic of the adept or of the spirit. This is a cycle which is completed in approximately eighteen of your diurnal cycles.

The spiritual, or adept’s, cycle is an eighteen-day cycle and operates with the qualities of the sine wave. Thus there are a few excellent days on the positive side of the curve, that being the first nine days of the cycle—precisely the fourth, the fifth, and the sixth—when workings are most appropriately undertaken, given that the entity is still without total conscious control of its mind/body/spirit distortion-reality.

The most interesting portion of this information, like that of each cycle, is the noting of the critical point wherein passing from the ninth to the tenth and from the eighteenth to the first days the adept will experience some difficulty, especially when there is a transition occurring in another cycle at the same time. At the nadir of each cycle the adept will be at its least powerful but will not be open to difficulties in nearly the degree that it experiences at critical times.

We may say that while these information systems are interesting, they are in sway only insofar as the entity or entities involved have not made totally efficient use of catalyst, and, therefore, instead of accepting the, shall we say, negative or retrograde moments or periods without undue notice, have the distortion towards the retaining of these distortions in order to work out the unused catalyst.

This cycle is an helpful tool to the adept; but, as we said, as the adept becomes more balanced, the workings designed will be dependent less and less upon these cycles of opportunity and more and more even in their efficacy.
