Our compatibility charts depict a range of days centered on the target day. The numbers -14, -7, +7, and +14 across the top mark dates ranging from the past to the future. The numbers from +100% (maximum) to -100% (minimum) indicate where the rhythms are on a particular day. In general, a rhythm at 0% is thought to have no real impact on your life, whereas a rhythm at +100% (a high) would give you an edge in that area, and a rhythm at -100% (a low) would make life more difficult in that area. There is no particular meaning to a day on which your rhythms are all high or all low, except the obvious benefits or hindrances that these rare extremes are thought to have on your life.
Compatibility: When looking at the biorhythmic relationship between two people, the key thing to understand is that we are looking at phase compatibility. In other words, 100% physical compatibility between two people does not mean that the relationship will be in a physical high all of the time - it means that all of the highs and lows between those two people will match. With this in mind, it may be clearer that when you look at a biorhythmic compatibility chart, you are looking at the highs and lows of the relationship as a whole.
The three primary biorhythm cycles are:
Emotional: This cycle tracks the stability and positive energy of your psyche and outlook on life, as well as your capacity to empathize with and build rapport with other people.
Intellectual: This cycle tracks your verbal, mathematical, symbolic, and creative abilities, as well as your capacity to apply reason and analysis to the world around you.
Physical: This cycle tracks your strength, health, and raw physical vitality.
The three secondary cycles that derive from the primaries are:
Mastery: This is the composite of the Intellectual and Physical cycles. Mastery encompasses your ability to succeed at tasks and to obtain what you desire. This cycle also tracks athletic ability and the focus required to learn physical skills.
Passion: This is the composite of the Physical and Emotional cycles. Passion encompasses your motivation to act, and the drive that allows you to continue a difficult pursuit. This cycle also tracks sexuality in its purest form.
Wisdom: This is the composite of the Emotional and Intellectual cycles. Wisdom encompasses your understanding of the world, your role in it, and the things that are truly important to your life. This cycle also tracks the presence of mind that you need to make crucial decisions.
