Rahu conjunctions with a Graha show psychological influences that are becoming developed. Planets conjoined Rahu will likely be expressed with immaturity, as is the nature of Rahu. Ketu conjunctions show energies that are already developed and where we have much skill, yet we are trying to finish. Planets conjoined Ketu will likely have maturity and refinement to their expression, yet the native will not feel satisfied with their level of development.
Behaviorally Rahu will be over expressive and magnify or exaggerate the qualities of the planets he is associating with, especially through conjunction. This quality of exaggeration is how Rahu brings their forces into our lives. They may be exaggerated externally or internally as psychological forces, or both. All of this is dependant on the houses involved and conditions. Ketu will withdraw and collapse around the planets he is associating with, especially through conjunction. He will tend to hide those things from our view and the view of others as he focuses on them internally. Ketu will try to extract the purest essence from these planets. As such, we will only notice what is missing where Ketu is concerned. In can be stated that the stage of Rahu with a Graha is where the native is in the developmental stage of its energy, and Ketu is where this energy is being completed.
Ketu / Sun - The Ketu / Sun association shows very high levels of self-doubt and shows a native who is not likely to feel content with their worldly actions, they are be a perfectionist. No matter what they do in the world they will feel a sense of lack. The native is being freed from the ego and a need to feel confident and powerful as the skilled eye of Ketu watches every ego game and false expression of Self with disdain. The quality of surrendering their smaller Self to the highest Self is being developed. Many times this will show a Spiritual native. Usually this native has had a childhood where they felt isolated and were made to doubt themselves on a deep, core level.
Ketu / Moon - The Ketu / Moon association shows a native who experiences deep levels of doubt and criticism of their own mind and mental outlook. This is one of the most difficult placements as it can make for a deeply discontented mind and extreme moodiness. Typical worldly experiences and pleasurable emotions can lead to painful episodes under Ketu�s probing and watchful eye. Many of the moods are from past life events that overtake the native, and then pass. Smaller disturbances trigger mental episodes that neither the native, nor anyone else can control. Yet generally they are good at controlling the emotions as this placement shows, yet control is not the same as having the detachment to enjoy without longing or regret. .
Ketu / Mars - The Ketu / Mars association shows a native who is skilled in the use of where to exert their personal, will yet they will experience some frustration with how to express this more humbled approach. This native may find himself in situations where they are tempted to fight or do battle on principle. The scrutiny of Ketu / Mars will likely see the futility in such a battle, yet later they will doubt if that was the right thing to do. This behavior may lead to occasional explosiveness and destruction as the Ketu / Mars energy is also finishing the tendency to destroy and break things in frustration.
Ketu / Mercury - The Ketu / Mercury association is showing the mind at the point where all mental concepts are in doubt and the highest levels of discrimination are being developed. A very skilled person and one with a probing intellect will be observed. Yet Ketu�s presence will be keenly aware of the pieces of information they do not have, rather than the ones they do. This can create much worry and mental vacillation as they keep searching for more information to doubt. They are learning to act more on intuition and to use the mind for its highest purpose, to see through the mental traps that give us the illusion of understanding and give the false paradigm of security we base our lives on.
