Three reference points, not one
Ordinary Jyotisha reads a chart from one rising point. Jamakol reads from three factors at once: Udhayam, Aarudam and Kavippu. Learn these three and most of the system becomes legible; skip them and no Jamakol rule will make sense, because every rule is phrased as a relationship between them.
Udhayam — the matter asked about
Udhayam is the primary rising point of the Jamakol chart and stands for the thing being asked about. Ask about a marriage and the marriage is Udhayam; ask about a stolen motorcycle and the motorcycle is Udhayam; ask about a job and the job is Udhayam. Its time reference is the present and the future.
- It moves about once an hour, clockwise through the fixed rasis — faster than an ordinary lagna, which takes roughly two hours.
- It is derived from sunrise and sunset for the astrologer's own location, through the twelve Udhaya rasis of the day half and the night half.
- A strong Udhayam, or a strong Udhayam lord, supports a favourable answer; a weak or debilitated one makes a yes harder to reach.
- The house occupied by the Udhayam lord describes what is in the questioner's mind.
Aarudam — intention and what has already happened
Aarudam is the second Lagna-like point. It carries the questioner's intention and the past of the matter. Two people can ask an identical sentence with entirely different intentions behind it, and Aarudam is where the tradition looks for that difference.
- It changes every five minutes — twelve positions across an hour, taken from the minute of the clock.
- It can also be taken from a number between 1 and 108 given by the querent, which is how Jamakol handles a question posed without a usable timestamp.
- Its position relative to Udhayam matters directly: Aarudam falling in the sixth, eighth or twelfth from Udhayam is read as an unfavourable result — and even where something does come about, the tradition says the native may not enjoy it.
Kavippu — the deciding denial
Kavippu is the factor that makes Jamakol decisive. It is not a planet and should not be read as one. The teaching describes it as the strongest negative factor in the system, gives it the weight of ten Rahus, and grants it authority that favourable combinations do not override.
How Kavippu is found
Three things are needed: Udhayam, Aarudam, and the Surya Veedhi — the solar grouping selected by the sign the Sun occupies. The rule is a transfer of distance:
As far as the Surya Veedhi anchor is from Aarudam, Kavippu is that far from Udhayam.
So the procedure is: find Udhayam, find Aarudam, take the Sun's sign, read off its Veedhi and that Veedhi's anchor, count the distance from Aarudam to the anchor, then count that same distance forward from Udhayam. Because Aarudam changes every five minutes, Kavippu does too. Its motion through the chart is anticlockwise, against the direction of the other factors.
What Kavippu decides
- Kavippu in Udhayam is the strongest denial in the system. The question is answered no, whatever the matter was.
- Kavippu with the Udhayam lord damages the matter through the lord rather than the house.
- Kavippu in the house that owns the question denies that specific matter — the second for money and family, the seventh for marriage and partnership, the tenth for profession, and so on.
- Kavippu in a house unrelated to the question is not a denial. This safeguard is part of the teaching, not a softening of it.
Maandi — the shadow point
Maandi is a fourth factor, computed from a weekday figure added to the Sun's longitude, with separate day and night tables. The tradition examines it especially in questions of survival: is the missing person alive, is the patient in danger. Maandi arriving in Udhayam, or joining the relevant bhava or its lord, is read as an unfavourable indication for that matter.
The comparison to memorise
| Udhayam | Aarudam | Kavippu | |
|---|---|---|---|
| Stands for | The matter asked about | The questioner's intention | Denial |
| Time sense | Present and future | Past | — |
| Moves every | ~1 hour | 5 minutes | 5 minutes |
| Direction | Clockwise | Clockwise | Anticlockwise |
| Derived from | Sunrise / sunset | The minute, or a number 1–108 | Aarudam, Veedhi anchor and Udhayam |
Where to see all of this computed
In Rajvidya the Calculations screen of a Jamakol cast shows each of these figures with its intermediate steps: sunrise and sunset for your location, the length of the day and night halves, the Udhayam rasi and the rate used to reach it, the Aarudam block, the Sun's sign with its Veedhi and anchor, the Kavippu count, and Maandi from the weekday table. Nothing is presented as a bare result you cannot check.
Next: Jama Grahas and Jama Time, then Kavippu in the twelve houses. The full method is in the Jamakol Prashnam guide.
