Natural Friends of planets

Naisargika Mitra or Shatru: Natural Friends and enemies

Every Graha treats the other Grahas as its friend or an enemy.

Each Graha has a Moolatrikona Raashi. The Moolatrikona is the office of the Graha. The list of Moolatrikona Raashi is given in the Graha lesson.
The Lords of the Raashis in Upachaya Sthaanas and also in the seventh, from the Moolatrikona of a Graha are enemies.
We know the Upachaya Sthaanas to be the 3rd, 6th, 10th and 11th
The Lords of the rest of the Raashis are friendly to the Graha.

An Example will make this clear.
Suryas Moolatrikona is Simha. From Simha the upachayas are Tula, Makara, Vrishabha and Mithuna. The Seventh Raashi is Kumbha.
Therefore the lords of these Raashis are enemies to Surya.
They are Shukra, Shani and Budha.
The lords of rest of the Raashis will be friends of Surya. They are Budha, Mangal, Guru and Chandra.
We see from the above that Budha is an enemy as well as friend of Surya and hence it becomes Nuetral.
Thus Surya will treat Shukra, Shani (Raahu also because of its co lordship of Kumbha) as enemies.
It will treat Mangal (Ketu also because of the co lordship of Vrischika) as friend
And it will treat Budha either as a Friend or an enemy depending on the Raashi supported by Budha, more among the two Raashis owned by it.

To judge which Raashi is more supported by a Graha who becomes Nuetral, we judge by the following steps.

A) If the Graha is placed in one of the two Raashis owned by it, then it will favor the Raashi and the final friendship/enmity will be decided by that Raashi.
Say for example For Surya we have found Budha to be Nuertal but, if it is placed in Mithuna which is an Upachaya from Simha (the Moolatrikona of Surya) then Surya will treat Budha as an enemy.
If Budha, on the other hand is placed in Kanya then Surya will treat Budha as a friend.

B) If the neutral Graha is placed in the seventh from any of the Raashis owned by it then also it will favor that Raashi more.
Say for example: Budha is placed in Meena. This is seventh from Kanya and so it favors Kanya more than Mithuna and hence Surya will treat Budha as a friend.

C) If the Neutral Graha is neither placed in one of the Raashi owned by it nor in the seventh from one of them then it will favor the Raashi which is of a different oddity from the Raashi it is placed in.
