Natural friendship is written into the planets
Every planet carries a permanent list of friends, enemies and neutrals — its naisargika (natural) relationships. The Sun befriends the Moon, Mars and Jupiter, opposes Venus and Saturn, and stays neutral to Mercury. This table never changes; it reads the same in every chart ever cast.
Mars's only natural enemy is Mercury; Venus and Saturn leave him indifferent.
Two camps run the sky
Memorize the logic, not the grid. Sun, Moon, Mars and Jupiter form a royal camp — soul, mind, strength, wisdom. Mercury, Venus and Saturn form a material camp — commerce, pleasure, labor. Planets befriend their own camp and oppose the other, with a few telling exceptions.
Camp-mates Venus and Saturn call each other friends; both name the royal Sun and Moon enemies.
Friendship in the sky is not mutual
The Moon calls no planet an enemy — yet Mercury names the Moon his only enemy. Mercury calls the Sun a friend; the Sun merely stays neutral back. The table has direction: always read a relationship from the side of the planet whose feelings you are judging.
The Moon befriends Mercury; Mercury resents the Moon. Both hold at once — as on Earth, so in the sky.
Tatkalika — friendship of circumstance
Each chart adds a temporary (tatkalika) layer. Count signs from any planet, its own sign as 1. Whoever sits in the 2nd, 3rd, 4th, 10th, 11th or 12th becomes its temporary friend. Whoever shares its sign or sits 5th, 6th, 7th, 8th or 9th is a temporary enemy.
Jupiter in Aries, Venus in Gemini: Venus sits 3rd from Jupiter — a temporary friend, despite their natural feud.
Panchadha maitri — five grades of relationship
Now stack the layers; each casts one vote. Friend plus friend makes a great friend (adhi mitra). Friend plus neutral stays a friend. Friend plus enemy cancels to neutral. Neutral plus enemy makes an enemy. Enemy plus enemy makes a great enemy (adhi shatru). Five grades — the panchadha maitri.
Sun naturally befriends Jupiter; Jupiter sitting 11th from him adds a temporary vote. Friend + friend = great friend.
Dignity's middle rungs live here
The dignity ladder's friend's-sign and enemy's-sign rungs read this compound table, not the natural one alone. A planet residing in a natural friend's sign can still slide to neutral — or climb to great friend — depending on who sits where in that particular chart.
Mars in Aquarius lodges with Saturn, a natural neutral to him — the temporal layer casts the deciding vote.
The one idea to keep
Compound before you judge
Friendship has two layers — nature and circumstance. The permanent table gives a planet's disposition; the chart gives the moment. Always compound the two before judging a residence.
