Since the Nodes as are not real points in the usual astronomical sense, and they are not visible or objective planets, their meaning takes on a enigmatic and mysterious vibe in the horoscope. Vedic astrology views the nodes as particularly malefic with the belief of a 'shadowy' nature cast over the individual, their significant use in a astrology has always followed a rather esoteric route and they are especially applicable to the sense of their being a karmic path to follow. In other words, the nodal axis acts as a straight line leading backwards into a previous existence and a repository of all previous wisdom (SN) and heading towards the future. It is also known as the 'line of fate' and the nodal axis is thought to shed considerable light on karmic destiny. Moreover, it takes in the whole mystique surrounding reincarnation and that life is one long continuous thread and life and death are only phases moving from one existence to another. The evolutionary path of the individual can be gleaned by analysing the nodes in the natal chart, and people that enter our life under a significant transiting planet to the nodal axis - enter the picture under extremely fated conditions.
The Astrology of the Nodes - Nodal Axis
From the point of view of psychology, astrologically speaking, mostly in terms of the unconscious and conscious. The South Node represents habits and routines without much consciousness, similar to sleepwalkers.The SN is what is already there in the personality, and the NN pulls the individual towards the creative spirit and asks us to exert the self into a particular direction with conscious and sustained effort and which will determine the direction of one's future. The North Node is where we need to become more conscious and 'switch on the light' by attending to its activities and being engaged. The South Node can be thought in terms of reading a whole paragraph of a book 'absent mindedly' without taking in a single word. When we know how to do something instinctively and we have complete knowledge. One professor of psychology said, “When I have to give a lecture I turn my mouth loose and go to sleep." With the nodal axis we need to switch from the automatic to the minding or 'mindful' behaviour and to make more conscious decision making.
Additionally, astrologers must never forget that the nodes form an axis and that their meanings are complementary, The main task of the nodes is to integrate both into the being. The interpretation of the actual cycle of the nodes and the continuing cycles of our lives as a process along a time-line and can also be viewed as particular points of reflection.
The year prior to each of these four nodal returns (19, 38, 57, and 76) is a sort of 12th House phase of the nodal cycle – a time in which one should attempt to sum up the meaning and activity of that entire cycle and prepare for the next. The age of 18 for example, is a time to sum up the experiences of one's youth so that an individual may develop an objective foundation for the new departure into adulthood at 19...At the second nodal cycle at age 37-38, one should try to assess the degree of success (or failure) in his attempts to realize his ideal life-purpose through concrete activities...When the third nodal cycle ends at age 56-57, each person should assess the degree of personality fulfilment he has achieved, and the measure to which his creative work as a social individual has been successful...and a time of change in spiritual direction...The fourth nodal return occurs at age 75-76. At that time there should be an assessment of the personality;s spiritual realizations, and of the success of one's efforts to conclude his life in a significant manner, leaving a seed to nourish future generations.
