Nakshatra ruled by Mercury and Ketu – Ashlesh, Mool, Revati, Jyesth and Ashwani are called Gand Mool nakshatras. If the natal Moon in the horoscope of a child is in one of these Nakshatras, the child is said to be born in Gand Mool Nakshatras.
According to P. Khurrana, child born in these nakshatras is inauspicious and faces various obstacles and problems in life, pooja should be performed within 27 days. Newly born child is also not considered lucky to the near relatives like maternal uncle, father, mother etc.
Some astrologers have difference in views and such as – Mool, Jyesth and Ashlesha are more inauspicious.'Jyotish Tatwa' states that starting 5 hours of Ashwini, magha and Moola and ending 5 hours of Moola, Jyeshth and Ashlesha are called "Gand Mool Nakshatras".
Some have the views that if the child is born in such Nakshatras, it signifies death of cattle, bad by heart, bad for maternal uncle, bad for elder brother, bad for spouse, death of father and death of mother etc.
Why will these ill effects come into picture is not clear. These ill effects are not mentioned in classical texts and not even astrologers know about it.
Now let us understand what are the rules of the results of planets in astrology.
If a planet is benefic good results are going to pass and its dasha will give good results. Therefore if in a horoscope or for a native, Mercury or Ketu are benefices and he/she is born in that Nakshatra, these planets and their dasha will give good results. It means we can not generalize the statement that if a child born in Gand Mool Nakshatra always give bad results will come to pass. This means if planets are malefic bad results will come to pass. The Nakshatra of any other planet can also be bad whereas that of Mercury and Ketu good..
Some of the people who born in the Gand Mool nakshatras and rose to great heights in their lives are Jawahar Lal Nehru, Mahatma Gandhi, Devanand, Nargis Dutt,Sunil Dutt,Amitabh Bachan ;Hrithik Roshan and the list is countless.
However, in every dosha the results should not be taken in a serious view from the "Name of Dosha" because our shastras lay down the system of pooja, paath, prayers, donations which can of course rectify any dosha ,as Gandmool Dosha under reference. Other than Gandhool Dosha there is existence of many yogas in the new born child as Raj yoga, Ekabli yoga, Dhawj yoga, Amar yoga, Gajkesari yoga, Hans yoga, Sihasan yoga (may be more than 1000 yogas) which play an important role at the time of birth and in further life. Under the yogas parents and other many relatives are affected. As I said there is nothing to be worried about because the "Upaya for Gandmool" is quite simple but it shows be done accurately. In the absence of this the repercussions could be hazardous. The best example relating to Gandmool Dosha is that as a polio drop is given to the infants to avoid any complications in the deformity of the body as the child converts into an adult. Likewise; the process of rectifying the "Gandmool" is within the means of everybody so there is no harm in doing the pooja to over-come the complications of the life.
