One of the most important planet in a horoscope is the moon. Kemdrum Dosh or Chandra Dosha happens when moon placed not in its usual houses, that is, not in house number 3,6, 7, 10 or 11, then it emits negative energy which is bad for a human being. Since the planet control human emotion, health, will power etc, when there is a negative influence on these things then the situation gets bad for humans. Thus one needs to perform Kemdrum Yog dosh or Chandra dosh nibaran Puja in order to prevent such negative influences.
