The North Node indicates the challenges the native is ready to face in order to show that he can accept new things I life, and live up to his/her potential. Chiron represents deep-seated pains the native finds hard to overcome. Any area of service and aiding others needs to be conquered by the native in a slow, conscious, and practical fashion. The resistance means that there is pain that will need deeper understanding. Remember that pain is the dying energy. This can turn the native an expert healer, and teach others how to heal and self-heal. Zane B. Stein observed how “The average person born with Chiron conjunct North Node tends to talk a lot about how s/he wants to achieve the great things represented by the natal house occupied by Chiron—-but constantly returns to doing things as s/he has always done them at the South Node.” So the main focus here is on the conscious effort, for the maximum beneficial experience.
More from Mr Zane B. Stein on this aspect. It resonates with the 6th house of work:
Like Donna Van Toen, I feel that the North Node is a point of growth, a point of untapped potential … To get at this potential you have to work darned hard. With Chiron here … the individual must work even harder, initially. [I’ll explain, later.] At the South Node, on the other hand, are those talents and abilities that are so much a part of you, that you do not need to develop them further. If you use them for yourself, you get into a rut, and end up feeling that you are going nowhere. If you use them for other people, it is like taking money from an unlimited trust fund—-you always have enough more to give. Now any person has the tendency to rely upon the South Node, rather than to strive in the direction of the North. But the person with Chiron on the North Node has a double difficulty: not only the normal human nature to follow the South—-but also, it takes a conscious effort to search for the pathway represented by Chiron—-to seek the teacher, the guru, the light.
