When the Moon crosses the node point, it wobbles slightly in it's orbit due to the gravity field generated by the node. The node is an inidicator of a junction of planes- the plane on which the Earth and Sun relate- when the Moon crosses that, he is affected by their presence in space. An eclipse is when they are all 3 aligned. Normal, non-eclipsed conjunctions are all other times- the moon crossing this plane, but not in direct alignment with the other two. So eclipses are the most intense nodal conjunctions because they carry the additional gravitational effect of alignment along with "crossing the plane".
The Moon's orbit is not along the eliptic, but has it's own angle. Hence it sometimes "rises above the Earth" and is sometimes "below the Earth". When it comes up, that is crossing Rahu. When it sets, that is crossing Ketu.
So these are all necessary things to know to easily interpret these conjunctions in a human chart.
In both cases, you must first understand that the wobble of the Moon is because of gravitational forces that are generated by the Earth and Sun. This translates to "sensitivity to vibrations based on the interactions of the souls and the field of action", or, "sensitivity to the manifestations of desire and ego". The Sun is the soul, the ego, the being, and the Earth is the field of action.
So these people are always sensitive, usually therefore more mentally hyper, and often therefore seen as difficult, "weird", psychic, abnormal, outcastes, depending on many factors.
The rising of the Moon above the Earth represents awareness. The Moon is trying to come above to protect, to cover and shelter. The Northern course represents the caring of the Gods for all beings. The other course, which begins at "Ketu's gate" for the Moon, and which also therefore lasts a fortnight as does the other, represents the Moons giving up care, or renunciation, being "under" all things taking place here, and overwhelmed by them. Rahu is the incoming breath of the Moon, and Ketu the outgoing.
Those born with Ketu conjunct Moon are overwhelmed in their feelings of sensitivity, and feel the need to retreat to counter this feeling. Therefore, those with Rahu Moons will be more involved, and actually argue and carry on like they care about everything, whereas those with Ketu Moons are more disinclined to be ivolved, and tend to philosophize away the problems they are sensitive to. Rahu is involved, Ketu is retreating.
Wherever is Rahu there will be some involvement there- things of that house run more out of control, and cause us to be involved in the material world- the matters of that house have a hook of obligation, so it feels, into our souls, and makes us to act and perform here. This will be a house very hard to renounce- very hard to ignore.
Ketu on the other hand creates a vacant house often- of the feeling thereof- therefore some will strive to fill it- therefore sometimes Ketu causes great success in the matters of the house where it rests in a persons chart- due to causing them to ever pursue "filling" that emptiness. It can make things ethereal and unseen- like me, I have thousands of friends, but I never see any of them (Ketu in the 11th).
Sri Caitanya, the greatest personage of this Yuga, was born on a raging full Ketu eclipse rising. He was a genious, but his sensitivity tore away at his mind, and most considered him crazy. He was highly sensitive and visionary, to say the least. Normally persons with nodal conjunctions will take to the sensitive arts, the arts, drugs, religion, seclusion, or revolution, or anything other than normalcy. They are usually outcastes or eccentric in some obvious way.
