Thank you for your reply. I tried every possible means to propitiate with ketu (including visiting temples, making poojas, reading sloka and wearing gem stones) and Ganapathy too. It seemed something against me is too strong that I cannot break the hurdle. I get to last stage of getting success in my career in finding a good job but break down to square one due to unexpected sheer bad luck which has no connection with my skill. All my hard work for the past two years went waste. It seems like a powerful curse is against me and I am totally clueless.
All I got out of this Ketu Dasa is acquaintance with astrology and bad memories through bad experience that I find difficult to take further steps ahead in life. I fear I may lose my good qualities due to frustration.
