Let's 1st understand what these planets represent on their own?

Saturn - It is all that which we don't like in our life. Saturn is Delay, Frustration, Restriction, Limitation and Anxiety. It is people of Authority, like Boss at your Work Place or Father-Figure at Home. Saturn is our Karmic Debt from past-life. Saturn is the things we didn't treat too well in our past life. Saturn is our Challenges and Lessons of life. Saturn is Old-Age, Teeth/Bones in Human Body, Diseases, Changes etc. Saturn represents our Step-Relations, it means that wherever Saturn sits, people related with that house give us Step Treatment. Saturn is Hard Work, Efforts and most importantly Perseverance etc. Nothing comes easy and in one go with Saturn. You have to work hard continuously over the longest possible period of life. Saturn makes a person Legend as Legends have one thing in common that they choose one field and work hard in it for whole life. 

Rahu - It represents Illusion, Foreign Lands, Foreign Things (foreign as in unknown things. So, for someone living in Punjab, culture and rituals of Kerala is also unknown and hence Foreign), Drugs, Medicines, any type of intoxication, Fame, Wealth, Success, Obsession, Past-life incomplete Desires, Movies, Television, Online World, Cheating, Imagined Fears, Unusual Things, Unique Things, Creativity, Rule breaker. Rahu also blows things out of proportions.

House Ruler - Besides these karaka things, Saturn & Rahu will also rule some houses in your chart and will represent things related to that house. Of course we can't cover conjunctions Ascendant and house wise else it will never be over. So, you have to include those things at the time of interpreting this conjunction. Also, we need to keep in mind all Yogas and Raj-Yogas which their conjunction would be making to completely understand the conjunction. Here, we can only cover meaning as per karakas. 

Meaning of Saturn-Rahu Conjunction - Although we have talked about stressful conjunctions and planetary war-zones like Saturn-Mars, Saturn-Sun and Rahu-Mars but this one can be considered as the most stressful conjunction among all. These days it is named as Shrapit Yoga or Cursed Combination of planets, which is given more for the purpose of selling gems/remedies, but even if we don't want to go into such scary names then also we have to accept that it is the most malefic conjunction among all. I know it very well as I have it in my chart. The closest in results to this malefic conjunction is Saturn-Ketu conjunction which we will discuss tomorrow. 

The reason behind it being the most malefic conjunction is their exact opposite nature. Rahu is our obsession, which wants to achieve everything right now. Saturn is our delays, frustration and perseverance in life. Saturn will give only after considerable delay in life, mostly after mid-30s, and that too after serious hard work & perseverance. So, a tug of war continues within person with this conjunction where Rahu pushes him to achieve something quickly but then Saturn puts a block in the way by indicating that you will get it with great delay and hard work. This only leads to frustration in individual. 

Suppose someone has this conjunction in 5th house. Then person would dearly want to be in love/romance like situation ASAP due to Rahu but Saturn will always give stress in relation. So, end result is bitter break-ups. And till mid-30s, this story can be repeated numerous times. Same thing can happen in other matters of 5th house too like Child Birth, Sports and Education. Person may be desirous of getting these results due to Rahu but Saturn will always delay the matter by putting some blocks on the way or making them to act repetitively to get the desired result. Like this, this conjunction can provide stress and frustration in major portion of life. Another ways of looking at it is that Rahu takes over the traits of the planet it sits with and then explodes it out of proportion. So here, Rahu is 1st taking over the traits of Saturn which are delay, frustration, hard work & perseverance and then exploding these traits out of proportions. Hence, making it a case of double hard work, double perseverance, double delay and double frustration. The only way out of this conjunction is to surrender yourself to Saturn's wishes. It means to put extra hard work up to the longest possible time and then wait for Rahu to give results with patience. You have no other option but to total surrender. 

Who will win the Conjunction? - Saturn will, at any day. 

Dignity & Strength - 

As Aquarius is ruled by Saturn-Rahu, these two together can give a few percent relieving effect there. Else anywhere it is same. 

In Aries, Cancer, Scorpio & Leo, the effects can go worse but there is no sign where this conjunction can become a positive one. Only one positivism which comes out of it is that person becomes very hard working as nothing comes in life easily. 

I will finish this article with a small portion of interview of an athlete - 

Journalist - How does it feel to become an overnight star?

Athlete - Yes, it feels great to become overnight star after 15 years of hard work with my trainer on improving my skills. 

This is the best way to represent Rahu-Saturn conjunction.
