Guru and rahu combination is very bad.
Strong evil forces encircled your luck.
The bad yoga is called Guru chandala yoga,which
is very bad for luck.
Further ,Rahu is also spoiling other planets,as
you wrote that Rahu is with three other planets.
You have to do penance for 2 years,to reduce Rahu

I am not an astrologer, but what i read so far shows, Guru+Rahu does make ahandal yoga, but this is not always as bad. As per probability it is very common. But apart from what is there, I am more interested in any remedies, if any.
Thats what I only can do now.
Some pandits said me to wear Manik in silver (as gold is not good due to some rahu effect here for me)
some japs of rahu, shani, guru and mangal are suggested.
