Ketu is the planet which represents separation, isolation, spirituality, and past lives! Moon represents mind, emotions, etc when Ketu and moon are in conjunction you may feel a bit detached, you may find yourself thinking a lot about your past! Past memories may surface up! You may come across people and events that are very karmic! Do not become critical about yourself! Pray to Lord Ganesha who rules over Ketu and make this transit a spiritual experience!
