is my mars damaged????...I have mars conjunct rahu in libra 6th house(tuaras asc)chitra nakshatra...I am in mars dasa what will happen???

This is the period when you will make some gains and also have serious troubles. Mars and Rahu are not compatible to each other. Rahu is strong in Libra. At the same time Mars being 12th Lord in 6th house is also strong. Two strong non-compatible planets in one place, means trouble relating to the matters for which those 2 planets are controlling in your life. So there will be problems in areas relating to your 6th house, 7th house, 12th house and also your own mental condition.

Yes, it is afflicted. Mars conjuncts Rahu and confers Angarak Grahan Yoga. Rahu in the signs ruled by Venus is really not that severe still I will warn you against your enemies. Again Mars being the 12th lord in 6th confers Vipareet Raj Yoga too so a hard earned victory is likely in this mahadasa of Mars.

Nothing. It's hogwash for idiots.
