Transits to the north node if having an echo in the natal chart, are an opportunity to get on your right path in that house or houses affected by the NN ruler. People may come along whose suns are on your NN or SN. They will help you but may not stay around. If we go to the SN conditions which are familiar and comfortable we will find no satisfaction there and must head off in opposite direction. The trick is to incorporate our SN previous experiece with our new NN conditions and meld them for advantage.
I wouldnt use any more than 1-3 degree orb.
