Ishta devata by the karakamsa method, from atmakaraka to deity

Last updated 25 October 2026

Enter your birth date and time to follow the classical chain from the atmakaraka to its navamsa sign, the karakamsa, and on to the sign the karakamsa method reads for the chosen deity. The text below explains each step, the verses behind the pairings, and how to treat a result this personal.

How the calculation works

The karakamsa method reaches the ishta devata in a chain of four steps, and the calculator shows each one so that you can check it.

1. Identify the atmakaraka. Whichever planet is deepest into its own sign, exactly as on our atmakaraka calculator. The seven-karaka count (Sun to Saturn) is the main result; the eight-karaka count, with Rahu measured backwards from the end of its sign, is shown as well whenever it gives a different atmakaraka.
2. Locate the karakamsa. Look up where the atmakaraka falls in the D9 (navamsa) chart. The chapter on the karakamsa in Brihat Parashara Hora Shastra begins by defining it this way.
3. Step back one sign. The sign just before the karakamsa is its 12th. The calculator notes every planet the D9 chart places there, the two nodes among them. The verses do not say which chart to use for this step; the navamsa is this calculator's reading, and a common one among Jaimini teachers.
4. Look up the classical pairing. The deity the verses associate with each planet found in that sign.

You supply a date, a clock time and the offset from UTC where the birth took place; a listed city merely sets that offset for you. Positions are sidereal, with the Lahiri ayanamsa, and the nodes are the mean nodes, with the true-node result compared and any difference stated. The Moon passes through a whole navamsa in roughly six hours, so the tool looks two hours before and after your time and reports any link of the chain that would differ. If you tick the unknown-time box, it sets out the seven-karaka chain for each part of the day instead.

The verses and how the calculator applies them

The pairings are taken from the karakamsa chapter of the Parashari text; the verse numbers below are those of the edition the calculator follows. The planet–deity pairings below follow that edition too; other editions and lineages number the verses differently and do not always pair the same deity with a planet. Most of the verses are worded as Ketu standing in the 12th together with a planet. Rahu and Ketu alone each have their own clause.

The calculator is explicit about how closely your chart matches the text. When the verse's condition holds, for instance Ketu really is with the Sun, the row says so. When a planet is in the 12th without Ketu, the same deity is shown but marked as an extension of the verse. Ketu sharing the sign with other planets defers to their verses; its stand-alone clause is then set aside. If the sign is empty, the text names no deity; the calculator then shows the sign's lord and its pairing as a labelled convention of its own. For Vrishchik or Kumbh it also names the Jaimini second ruler and leaves the choice open.

Reading the result with care

This is the most personal result an astrology tool can give, and astrologers handle it in very different ways. Some practitioners use the Jaimini pointer as described here. Others read the same 12th from the karakamsa in the birth chart instead of the navamsa, look to the 5th or 9th house for devotion and dharma, or use a further divisional chart for spiritual matters. In many families the question never comes to astrology at all, because the deity is part of family life and personal experience.

A responsible astrologer will treat the result as a pointer to discuss, not an instruction. If you already feel close to a deity, that relationship is what matters, and a good practitioner will say so. If the chart points somewhere you find unfamiliar, it may be read as an aspect of the divine to understand better, not a replacement for your own practice. No part of this result should be used to pressure anyone into rituals, purchases or a change of faith; our guide to warning signs of a fake astrologer covers the tactics to watch for.

It also helps to remember what the karakamsa is for. Jaimini practitioners use it as a lens on the soul's inclinations as a whole, and the 12th from it, the sign of release and liberation, is only one of many signs read from it. A consultation that treats the ishta devata as a magic key, cut off from the rest of the chart, is doing less than the tradition asks.

Questions to ask your astrologer about the ishta devata

• Do you read the 12th from the karakamsa in the navamsa or in the birth chart, and why?
• My 12th from the karakamsa is empty. How does your tradition handle that?
• How do you tell the ishta devata apart from my family deity?
• My atmakaraka is nearly level with another planet. Would the other one change the karakamsa?
• Is this pointer something to reflect on, or are you suggesting a specific practice, and on what basis?
