The Ishta Devata is the form of the divine a chart points to for worship aimed at moksha - release - not a lucky charm for a job or a marriage. In the Jaimini method used on this site, it is read from the 12th house counted from the Karakamsa in the Navamsa (D9). That is a different question from the family deity (Kula Devata) or the village deity. Those are inherited. This one is personal.
It is also a sequel to the Atmakaraka and Darakaraka guide. The Atmakaraka is the planet at the highest degree - the soul planet. The sign it occupies in Navamsa is the Karakamsa. From that sign you count twelve houses, as if the Karakamsa were a Lagna of its own. What sits in that 12th, or aspects it, or rules it, names the deity.
Karakamsa is a Navamsa fact
Navamsa divides each sign into nine parts of 3°20'. The Atmakaraka can sit in Mesha in the birth chart and in Dhanu in D9. The Karakamsa is the D9 sign, not the rasi sign. A small error in birth time can move that sign and change the answer. If the time is rounded, treat the result as provisional. Find the planet first on the Atmakaraka calculator, see the Navamsha counted from that sign on the Karakamsha Chart, then the deity on the Ishta Devata calculator.
Occupant, aspect, then lord
The engine on this site uses a fixed order, the same order as the calculator:
- Occupant. A planet sitting in the 12th from Karakamsa in Navamsa wins. That planet maps to a deity.
- Jaimini rashi aspect. If the 12th is empty, a planet whose sign aspects that sign by rashi drishti is used. Movable signs aspect fixed signs except the next one; fixed signs aspect movable except the previous; dual signs aspect the other duals.
- Lord of the 12th. If nothing occupies and nothing aspects, the lord of that sign names the deity.
The planet-to-deity table is traditional and not unique. Sun to Shiva, Moon to Parvati, Mars to Kartikeya, Mercury and Jupiter to Vishnu, Venus to Lakshmi, Saturn to Hanuman, Rahu to Durga, Ketu to Ganesha - with classical alternates on each line. Teachers disagree. Treat one result as a door, not a correction of a love you already have.
Pick the Atmakaraka, then the Navamsa sign it sits in (the Karakamsa). House 1 is that sign; house 12 is the Ishta house. Optionally place a planet there.
Atmakaraka
Karakamsa (D9 sign of the AK)
Planet in the 12th (optional)
Lord Subrahmanya (Kartikeya)
Guru in Dhanu Navamsa. 12th is Vrishchika (Scorpio).
No occupant is set, so the lord of the 12th points to the Ishta. Worship is a moksha practice, not a lucky charm.

Stay with a deity you already love
Every tradition that uses this method also says a genuine connection outranks a calculated one. If you already sit with Krishna, Durga, Shiva or a family form with a real heart, do not abandon that because a chart named someone else. Read this as an additional door - a mantra, a temple, a Tuesday - not as a rebuke. The calculator on this site says the same thing on the result.
Worship here is practice toward moksha: patience, surrender, a form that steadies the mind. It is not a transaction for a visa or a wedding date. Those questions belong to dasha, the 7th house and ordinary effort. Mixing the Ishta into a lucky-charm shop is how the method gets sold, not how it is used.
How to check yours
You need an exact birth time, because Navamsa is fine-grained. Find the Atmakaraka, confirm the Karakamsa, then run the Ishta page. If two planets compete - occupant and aspect - the occupant wins on this site. If your time is uncertain, stay with the deity you love and treat the calculation as a maybe.
A chart can name a form. It cannot replace a guru, a temple, or the years of sitting still. The Ishta is a good name for a practice. It is a poor name for a shortcut.
