Harihara's 17th-c. Kerala tradition
Hold one specific question in your mind. The ascendant rising at this very moment becomes your chart. Add a number 1–108 (the sankhya / aarudha) and any omen you just noticed (nimitta) — Kerala Prasna weighs both.
You can hold the question silently in your heart. The prashna kundali still reveals the matter and its outcome. Reveal the question later as a top-up if you wish.
Your natal chart has no birthplace saved. Share where you are now, or enter the latitude/longitude of your natal place — the prashna lagna is cast for this point.
