Capricorn is the 10th house for the aries ascendants… Lord of Capricorn is Saturn which is placed in own sign in the 10th house of karma.

Capricorn sign reflects the true nature of saturnian personality such as hard working, self disciplined, realistic, lawful, honest, sincere, serious, fearful so normally placement of Saturn over here in 10th house will boost us these quality in the person when he is on duties either on personal or on professional ground of life…

Now let us discuss about Rahu, Rahu is illusion, shadow, unreal, obsession, misleading, dishonest, in-disciplined so these Rahvik energy will overshadow the sensitive energy of saturn. Rahu – Saturn conjuction will make person diluted in saturnian qualities such a lesser sincerity, honesty, discipline etc. In addition, person would be prone to take the short cuts to achieve his obsession which is contradictory to capricorn nature.. so here Rahu will manipulate the saturnian energy of capricorn. & He would be caught in some scam later in either Rahu or Saturn or both dasas.

Moreover, Rahu is lord of aquarius which is here 11th house which means house of gain… Aquarius is the sign which is very creative, communicative, expressive and enjoying form of saturn. because it is co-owned by both saturn and Rahu.. Here both these co-lords are in the 12th from its sign.. so 11th house’s fruits such as big friend circle, sharing and caring for friends, communicative nature, creativity and enjoyment would be lost. and further it would delay/reduce the realization or achievement of gain in the life.

So overall in one paragraph, as person’s saturnian qualities such as hard work, honesty, realistic approach etc gets diluted by Rahu, the gain/fruits of his karma get adulterated and will have losses in their dasas. so learning here is to avoid the obsession to take short cuts in career or gains.
