Combust Horaअस्त होरा
A planet is "combust" when it passes too close to the Sun in the sky, astronomically overwhelmed by the Sun's light — classically considered to weaken that planet's significations. This warning fires whenever the ruling planet of the current (or an upcoming) Hora is combust.
If, say, Mercury is combust and you're in a Mercury Hora, the Hora's usual "good for business, communication, education" guidance is undermined — the message spells out specifically what to avoid for that planet while combust (e.g. Mercury combust: avoid finalizing documents or deploying anything without expecting a redo).
Combustion is a real, slow-changing astronomical fact (a planet stays combust for days to weeks depending on which planet), re-checked at each Hora's own start time — since the Hora cycle repeats the same 7 planets roughly every hour, the same planet's Hora can recur several times in one day, and each occurrence is checked independently.
