BADHAK GRAHA ( OBSTRUCTING PLANETS):
Discussion Material by

radeep Goel : 20 Oct 2010
In Jatak Parijata: Acharya Vadyanath ji has stated that a Badhak Graha is any one of the following – for different lagnas :--For Char lagna (Moveable Lagnas ): The planets who is lord of 11nth house or is placed in 11nth house .- For Sthir lagna ( Fixed Lagnas ): The planet who is lord of or is placed in 9th
house .-For Dwishabhava Lagna ( Both Moveable+Fixed lagna ) :Theplanet who is lord of 7nth house or is placed in 7nth house.
Provided : the particular graha is also lord of Mandi ( anupgraha of Saturn also known as Gulika ) and / or is a “Kharesh”i.e. 22nd
Dreshkona lord .Normally while studying a horoscope we , as a student ofAstrology, consider the lord of 11nth house, 9nth house and7nth house for Char, Sthir and Dwishabhava lagnasrespectively as “Bhadak Planets” – and totally ignore thefundamental condition attached regarding the lordship of Mandiand / or 22
nd
Dreshkona . Learned Shri B.Subramanian Shastri jihas categorically clarified, in one of his articles, that the correct interpretation of the relevant shloka given inJataka Parijata is that “the planet becomes a badhaka – fordifferent lagnas as stated above ONLY when the same planet isalso lord of Mandi ( Upgraha of Saturn) and / or of 22nd Dreshkona” .
Practical implementation : in my humble view:
1. The literal interpretation and practical treatment of aparticular planet as Bhadaka should be taken in right spirit and not as a yard stick. This is just one parameter which develops a property of a obstruction/hurdle in a particular planet while giving positive results or it is just one parameter which adds tothe malefic influence of a planet.
It is not that the particular planet which surely comes under this category of Badhak –sheds its entire benevolence and is converted into a total 100%malefic planet============
from another source :
It is important to note that Maharishi Parashar has used Badhak only in reference with Chara dasha and not in general application. So should it be used with other dasa systems, especially Nakshatra based dasa systems like Vimshottari dasa, they way it is being used by present astrologers? For example, we don't see reference of badhaka in Vimshottari Dasa chapter, his favorite dasa to which he has devoted most number of chapters. Badhakasthana is a rasi based concept and it makes more sense to use it with a rasi based dasa like Chara dasa.
The point should also be noted that Mahirshi doesn't make any mention that the owner or occupant of badhakastha will prove malefic for the native.
Only lord can protect the wealth of correct astrological knowledge in this age of Kali , and pass on to those who deserve it. May lord bless me to become a deserver
