Rule behind friendship/enmity of planets

It seems I am breaking the series in between but I got few emails regarding how to decide friendship/enmity between planets as everyone seems to contradict with each other. I thought it is important to understand how I am saying that Saturn and Mars are enemies but Mars and Venus are neutral, to understand this lord through houses series also. It is better to post it right now then after series is over. So, posting the rule which is the base behind all enmity/friendship thing. If you understand this, you can decide by yourself about which planet is friendly/enemy to which planet. 

So, here is the rule. 

If you want to know if a planet is inimical, friendly or neutral to any planet then 1st of all make that planet's mool trikon sign as Ascendant. Then the lords of 2nd, 4th, 5th, 8th, 9th, 12th house from this ascendant and lord of its exaltation sign will be friendly to this planet (as these houses represent pleasant things of life like Family, Home, Romance, Marriage Relations, Knowledge and Spirituality etc respectively). Lords of 3rd, 6th, 7th, 10th and 11th house will be inimical (as these houses represent where we need to put Efforts, Work Hard, Compromise, deal with Authority of others and may need to let go of Desires etc respectively). If a planet is lord of a friendly house and inimical house both, then that planet will be neutral. 

So, here is the example - Suppose you want to know friendly, enemy planet of Jupiter. Jupiter's Mool Trikon sign is Sagittarius. Make Sagittarius as the Ascendant. 

Friendly Planets - 

Lord of 2nd house - Capricorn = Saturn. 
Lord of 4th house - Pisces = Jupiter itself. 
Lord of 5th house - Aries = Mars
Lord of 8th house - Cancer = Moon
Lord of 9th house - Leo = Sun 
Lord of 12th house - Scorpio = Mars and
Lord of Exaltation Sign - Cancer = Moon

Inimical Planets 

Lord of 3rd house - Aquarius = Saturn
Lord of 6th house - Taurus = Venus
Lord of 7th house - Gemini = Mercury
Lord of 10th house - Virgo = Mercury
Lord of 11th house - Libra = Venus

So, here is the final list 

Friendly to Jupiter 
Sun, Moon, Mars

Enemy to Jupiter 
Mercury, Venus 

Neutral to Jupiter
Saturn (as it rules one friendly and one inimical house)

Hope it is clear. Likewise, you can do it for every planet. :)

Please find below Mool Trikon Sign of every planet - 

Sun - Leo. 
Moon - Taurus. 
Mars - Aries. 
Mercury - Virgo (it is funny how Mercury's Own, Exalted and Mool Trikon sign is same). 
Venus - Libra. 
Jupiter - Sagittarius. 
Saturn - Aquarius. 

Just keep these signs as Ascendants and see which planets are friendly/inimical to the planet. 

Hope this is helpful. Please let me know if there is any query/doubt.
