When the nodal axis is involved, one has ‘fated’ or deeply meaningful encounters. Other people are usually part of the package involved with nodal activity, and because of the solar component, these people are often very important for our growth as individuals. They are connected in some mysterious way with our meaning and purpose in life.
Greene identifies nodal-axis contacts in astrology as the primary astrological signature of fated togetherness, linking such encounters to individual purpose and the coniunctio of Sun and Moon.
