Praśna is one of the oldest jyotiṣa-techniques and one of the most powerful when used with discipline. The premise: the moment a sincere question is asked has its own chart, and that chart contains the answer — not through magic but because the moment IS the question, in time-form. BPHS Ch. 91 and Jaimini Adhy. 4 · Pāda 1 give the canonical methodology.
The standard praśna-workflow: (1) note the exact time and place the question is asked; (2) compute the praśna-lagna for that moment; (3) identify the kāraka — the graha that represents the querent (often the lagna-lord) and the thing-asked-about (e.g., 7th-lord for a question about a spouse, 10th-lord for a question about career); (4) examine the relationships — is the kāraka well-placed? Aspected by benefics? Approaching a key transit? (5) interpret with restraint — praśna answers the specific question, NOT 'will this person be happy in life?'
Our /prashna surface implements praśna-lagna computation and key kāraka-significator analysis. The interpretive step remains the practitioner's responsibility. Praśna is not a fortune-telling shortcut — it's a disciplined technique with a long tradition, and its quality depends on the discipline of both the question and the interpreter.
