Orientation is not discussed in my book Journey of Your Soul because it is more recent material.
There are three universal forces behind everything: love, truth, and beauty. These correspond with emotions, intellect, and body; or inspiration, expression, and action axes. Beauty is also known as energy or pure energy, life, or vitality. Souls orient in one of them, or work with balancing two of these qualities. Someone with a truth orientation is more likely to be blunt about the truth she perceives, whereas someone oriented in love is more likely to forgive and let go of the trespasses of others, for example. Someone with a beauty orientation is more likely to cultivate his body and enjoy nature; it aligns with the action-axis affinity for physicality.
Although love aligns with the inspiration axis, and truth, with the expression axis, a priest can orient in the truth or beauty force rather than love, just as a sage can orient in love or beauty rather than truth. If a priest has a love orientation or a sage has a truth orientation, that reinforces her basic nature. Although scholars are neutral, interested in all experiences, a truth orientation underlines the scholarly love of knowledge. A beauty orientation supports endeavors such as energy work.
Someone with a combination love/truth orientation is constantly working to integrate these two forces: for instance, trying to speak both truthfully and kindly. Someone with a love/beauty orientation is about the intersection of love and beauty: the love of beauty and the beauty of love. With the combination of truth and beauty, one seeks the truth in beauty and vice versa.
This information is provided after the cadre/entity numbers on my Michael Reading charts because each soul must tie into a universal force in order to maintain the existence of the entity. Entities do not necessarily have equal numbers of each orientation, but cadres are likely to.
Orientation is different from the three entity sides in raw number casting.
