Sambandha: Relationships.
Relationships form the bedrock of our Human society and they are also reflected in Jyotish.
In Jyotish the relationship between Grahas should be understood to know how, two or more Grahas will interact to bring about a particular event.
There are different types of Sambandha and we will study two of these.
A) Bhaava Sambandha - Mutual placement of two grahas from each other:
I) When the two grahas are placed in Kendra to each others.
This makes them having the same speed and hence they are co-operating with each others and they are called Paraspara Kaarakas (Mutual Significators). They will try to help each other in their significations. This is same as two cars traveling in the same lane in a highway and hence they maintain the same speed as to not obstruct the movements of each others. This is said to be a good Sambandha between the two grahas.
Example:



II) When two Grahas are placed in trikona (trine) to each other.
This makes them placed in the same Tatva (of the Raashi) due to which the goal (Aayaana) of the   Grahas becomes the same and this Sambandha is also a good or auspicious one.
Example:


III) When two grahas are placed in 3/11 from each other it shows grudging co-operation between the two. The common result they promise will be achieved after initial delay.
Example:


IV) When two Grahas are placed 2/12 (dwirdwadashaa) this shows wrong timing. Depending on other factors even if the two Grahas want to co-operate, wrong timing will not allow the result to fructify.
Example:


V) Two Grahas placed 6th/8th (Shadhaasthaka) from each other show a complete mismatch between the two. They will act inimical to each other.  
Example:

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.


B) Graha Sambandha:
Sambandha between grahas are also seen to see if they are willing to act for each other.
This may be called Graha Sambandha.
I) Parivartana: Exchange of Raashi between the two Grahas is called Raashi Parivartana and exchange between Nakshatras is called Nakshatra parivartana. We will only try to know about Raashi Parivartana for now. Raashi Parivartana means one Graha is in the Raashi of another as the other one is in the first Grahas Raashi. To explain it more clearly see the following example.


In the above chart Guru is placed in the Raashi owned by Shukra and Shukra is placed in the Raashi owned by Guru. This is Parivartana. This is 100% sambandha or Poorna Sambandha. The two grahas give their mutual result right from birth as also they give each others result.

II) Yuti – conjunction: When two or more Grahas are placed in on Raashi they are said to be in Yuti Sambandha. This is also Poorna Sambandha but of a lesser degree (Say 75%).
Sometimes more than two Grahas occupy a Raashi in which case it is called Koota Sambandha. In this case the most malefic (natural) will give the result of the most benefic (natural) and vice-versa.
The standard list from the most benefic to the most malefic is-
Guru, Shukra, Strong Chandra, Budha, Weak Chandra, Surya, Ketu, Mangal, Shani and Raahu.
Example:


In this Chart Guru and Chandra are in Yuti and hence will give results of each other.
Example (Koota Sambandha):


In the above chart there is a Yooti Sambandha between Shani, Raahu and Guru. This is a Koota Sanbandha. In this case Raahu being the most malefic will give result of Guru and vice-versa whereas Shani will tend to give its own result.
Remember it is not that there is a reversal of role of the Grahas but it is just that when timing the result of a particular Graha we have to be aware of these Sambandhas.
Paraspara Drishti: Mutual aspect.
Two Grahas Aspecting each other (Graha as well as Raashi Drishti) are said to have Sambandha. Graha Drishti is stronger of the two but of lesser strength than the above two.
Graha Drishti sambandha is called Bhavishyat Sambandha (Future fruition).                      


There are other types of Sambandha between Grahas but it is for a future lesson. Till then try to apply these Sambandhas in different charts starting with your own.

Hi Vivek-ji and Rishi-ji

Do the advancement of the planets make in diff to the sambandha ??? for eg in case of 3/11 of the planet is on border such that it may  occupy the nxt house and may cause 2/12 combi .. thus givin dome diff in interpretation. do the cusp located planets make diff to the sambandha ??


Warmly
Asro

Dear Vivek ji,
Please have a look at A(IV) and (V) in the above topic the pics are not  loading.Pleas re-load them

Namaskaar,
Raashi division is the natural division of the zodiac, the Raashis are overlorded by Surya as the Dwadasa Aadityas and hence all these sambandhas are Raashi bound. Secondly there is the Tatwa (Aayaana) and the mobility (Chara, Sthira and Dwishbhaava) classifications of the Raashis. Sambandhas are a direct results of this.
Like for example you are in a room with another person (A) and both are at a distance of say two feet from each others, then there is a person (B) in an adjacent room. You are hair breadth to the wall seperating these two rooms and (B) is also hair breadth form this wall, still there is no sambandha between you and (B) because both are unaware of each others presence inspite of being closer to each other compared to the distance from (A).  
Hope this makes it clear.
Try to keep things simple and you will have a clearer vision while predicting. An village Jyotish has very little knowledge of all these factors like the angular distance between Grahas, you see an hand made horoscope rarely had all these details mentioned in it but still the village Jyotish is able to predict much better than us (inspite of all our technically sound knowledge).
RishiRahul and vivek.

HI Vivekji

Thanx for the analogy of the rooms .. it does make things simple ...
