Jyotiṣa
The only one of the five never to break its transmission. Reads from a sidereal zodiac and organises time by period rather than by transit alone, so a transit is always read against the period it falls inside.
Who wrote it down
The authors are long out of copyright. Almost every English text of them is not — a modern translation is a living work of scholarship owned by its translator. So Jade paraphrases and names the chapter, and quotes directly only where an English text is itself in the public domain. Two of the nineteen sources are.

What each planet meant
Three answers for each: what this tradition took the planet to be, what it takes the planet to do, and what it makes of somebody born with it strongly placed. The third is the one that differs most between traditions, and the one a reading is built from.
Sun
- is
- Sūrya — ātmakāraka, the significator of the self, of the father, of bone and of sovereignty.
- does
- Illuminates, and scorches what stands beside it.
- in a nativity
- Read for the self that cannot be delegated. Strong, somebody carries responsibility without being asked; weak, they carry it resentfully, which is the same weight held differently.
Moon
- is
- Candra — the mind itself, manas, and the significator of the mother and of everything that fills and empties.
- does
- Waxes and wanes, and the tradition reads its brightness rather than only its place.
- in a nativity
- Manaḥkāraka, the mind, and in practice the placement a Jyotiṣī reads first. Well placed, somebody is at home in their own company; strained, the chart’s other strengths are harder for them to reach.
Saturn
- is
- Śani — slow, the significator of labour, of servants, of the poor, of longevity, and the one graha the tradition treats as a judge.
- does
- Delays, and settles accounts.
- in a nativity
- Śani is servant and judge. The doctrine is that it delays and then confirms: what it governs arrives late and does not leave, and a strong Śani is regarded as one of the better things to have.
Jupiter
- is
- Guru or Bṛhaspati — the teacher, the counsellor, and the greatest benefic; significator of children, of wealth, and of dharma.
- does
- Blesses and expands, and its aspect is read as protective in a way no Western tradition quite matches.
- in a nativity
- Guru, and the tradition means teacher literally — a strong Jupiter usually means somebody was taught early and it took. Weak, they have had to construct their own principles, later and at more cost.
Mars
- is
- Maṅgala or Kuja — a kṛra graha, commander of the army, significator of siblings, land, and courage.
- does
- Asserts, and holds ground.
- in a nativity
- Bhrātṛkāraka — courage, siblings, land, and the willingness to hold a position. Maṅgala is read for whether somebody will defend what is theirs, which is admired where it is warranted and named doṣa where it is not.
Venus
- is
- Śukra — the teacher of the asuras, significator of the spouse, of vehicles, of comfort and of art.
- does
- Refines, and attaches.
- in a nativity
- Śukra is what somebody finds beautiful and will arrange a life to be near. It is also read for the capacity to enjoy what has already been obtained, which is a separate skill from obtaining it.
Mercury
- is
- Budha — intelligence and discrimination, and the most changeable of the grahas because it takes on the character of whatever it sits with.
- does
- Distinguishes. It tells apart what had been lumped together.
- in a nativity
- Budha is discrimination: telling two similar things apart. Strong, somebody judges detail well; compromised, they are quick and wrong in a way that is hard to catch, because the speed is convincing.
Rahu
- is
- Rāhu — the severed head, a chāyā graha with no body, insatiable because it can swallow and not digest.
- does
- Amplifies and obsesses, and confers worldly result without satisfaction.
- in a nativity
- Unbounded appetite, and foreign ground — the part of a life that does not come from the family and is not explained by it. It gives worldly results and withholds satisfaction, which is the oldest observation about it.
Ketu
- is
- Ketu — the body without the head, the other chāyā graha; significator of detachment, of what is already finished, and of insight without ambition.
- does
- Cuts away, and leaves what cannot be removed.
- in a nativity
- Mokṣakāraka, read for where somebody is already finished, often without having noticed. It removes attachment to what it touches, which is loss or freedom depending on what was being held.
