South Node ILH Ketu is our comfort zone. What gives us the security that works easily and well known. This can be a talent, but also fears that we carry from a previous life. The conflict arises when it is related to the fear and knowledge, not using the talents of understanding comfort zone. To go outside the zone, which represents Rahu, we must first get to know, and that is Ketu.
South Node are our habits, something that leads us to behave in a certain way and feel the way we feel. These are patterns of behavior we and our ancestors molded to form concrete, tangible goals that can in turn lead, which prevents us from seeing their true purpose or the North Node.
