Frequently asked questions

What is an Ishta Devata?
The Ishta Devata is the deity most connected to your soul's purpose, determined in Jyotish from the Atmakaraka — the planet with the highest degree in your chart. Each Atmakaraka planet maps to a deity: for example, Sun to Shiva or Rama, Moon to Parvati, Mars to Hanuman or Skanda. Worshiping this deity is considered the most direct path for spiritual growth in one's lifetime.
How does this calculator find the Ishta Devata?
It first computes the Atmakaraka — the planet with the highest degree in its sign, with Rahu handled by reverse count — then maps that planet to its classical deity association as given in the Jaimini tradition. Enter birth details and the tool returns your Atmakaraka planet and the corresponding Ishta Devata, with a brief note on the deity's worship.
Is this the full Karakamsa method?
The calculator follows the classical Jaimini mapping from the Atmakaraka to its deity, which is the core of the Karakamsa approach. A full Karakamsa analysis also considers the Navamsa position of the Atmakaraka, the Karakamsa Lagna, and the planetary exchanges in that chart, which refine the deity's expression. This tool gives the foundational Atmakaraka-based deity; deeper chart work is best done with a Jyotishi.
