Namaskaar Raman ji,
1. What we meant and maybe were not able to put through was that the two Grahas in Shadashthak dont want to coperate with each other. When one wants to initiate some thing the other will not want it to happen and vice- versa.
As for the relation between the Kaaraka of a Bhaava and the lord of the Bhaava is concerned it may be the case (it is not a good sambandha). But more important is the relationship of the Bhaava and its kaaraka. Which means as to how the Kaaraka is placed w.r.t the bhaava.

2. Here 'Frienship and enmity' means the Natural and temporal frienship / enmity between Grahas. Actually the subject matter of the next lesson.

Namaskaar Raman ji,
In the previous post i may add a few things from the writings of a SJC Guru, Zoran ji in his blog.

"BHAAVA , BHAAVA LORD (BHAAVESHA) AND KAARAKA

Know the difference among bhava, bhaava lord and kaaraka. These three factors are essential to understand the nature and auspiciousness of a bhaava. For example, if Lagna lord is in Kendra or kona, then our brain functions well, and we easily make good decisions. This does not necessarily mean that a person is lucky. There is an other factor called “luck “ factor known as a Kaaraka.  


1.       Examine the Bhaava lord as counted from the Bhaava to see the resources of a Bhaava itself

2.       Examine the Bhaava lord as counted from Lagna to see whether a person will experience the resources of a Bhaava.

If a bhaava lord is well placed from the bhaava itself, then we can well use intelligence RELATED to that bhaava, our decisions are good. If a bhaava lord is well placed from Lagna, then such decisions are good for us, whatever the resources of a bhaava are. For example,  Take Mithuna Lagna and Budha in 4th house.From the 4th bhava it is well placed as a lord, so our decisions related to home, property, place where we live are good. We will choose a nice house, at a right time and money. However, whether such a house will be good for us, make us happy and prosperous, is seen from the position of the 4th lord from Lagna. In  this case , it is both, so good.

Kaaraka is the final authority of a bhaava. We may apply our intelligence very well, yet the luck may never come.

So there are two factors:

1.       Relationship of bhaava and a kaaraka

2.       Relationship of a bhaava lord and kaaraka

If a bhaava lord and kaaraka are in good relationship, we will make such decisions which will be supported by God, and our attitude is very good. It is the sign of a good karma related to that area of life. In opposite case it is akin to a curse."

Dear vivek and Rahul ji,
Thank you for explaning and replying to my query.I did understand that 6-8 relationship shows planets not being supportive to each other rather tryin to work against other,as u said
"When one wants to initiate some thing the other will not want it to happen and vice- versa"
Thus they dont want others task to get complete. For example :- any one of
karaka/bhaava/bhaava lord may want native get married but 6-8 relationship of this with other factors karaka/bhaava/bhaava lord may try to stop get it happen then doesnt mean that they r like enmical to each other coz though not just they r NOT  supporting each but also they r trying to stop others task getting done.


Please explain.

Regards,
Raman

Namaskaar Raman ji,
They may be called inimical only because of the placement from each others. This mutual placement (say for example Shadaashthaka) in the chart is te reason for the wrong timing between the two, otherwise they may be friends (natural, temporal or combined).
The above friendship and enimities is another matter altoghether. We did not want to confuse the two and hence the sentence in the lesson, which was quoted by you asking for clarifications.

The sentences qouted by you
"Two Grahas placed 6th/8th (Shadhaasthaka) from each other show a complete mismatch between the two. They will act inimical to each other "

"This Sambandha shows the mutual working for each other or the level of co-operation between two Grahas. It does not show support or the friendship or enmity amongst them"

The two sentences does appear contradictory, but we hope we have clarified to your satisfaction.
