Every verdict in Vyoma is a sum you can audit. Each rule contributes signed points, the ledger shows all of them with a running total, and the one-word band at the top is only a label for that total. Nothing is hidden and nothing is averaged away.

Panchanga means "five limbs": tithi, vara, nakshatra, yoga and karana, the five readings a printed almanac gives for a day. All five come from the same two numbers — where the Sun and Moon sit against the zodiac — divided up in five different ways.

Tara bala measures the relationship between a birth nakshatra and wherever the Moon happens to be transiting today, by counting the distance between them around the 27-nakshatra circle and reducing that count to one of nine named taras.

Chandra bala reads the transiting Moon's sign against the birth Moon's sign, sorting all twelve possible positions into favourable, middling and unfavourable — with the eighth position, chandrashtama, singled out as the one position severe enough to be scored on its own.

The ghatak ("destroyer") chakra is a table, keyed on the birth Moon's sign, of specific tithis, weekdays and nakshatras classically held to work against that birth sign in particular — a layer of affliction that exists independently of tara bala or chandra bala.

Day-yogas are a second, older layer of yogas from the muhurta tradition, unrelated to the panchanga's yoga limb or to chart combination yogas: they name specific pairings of weekday and nakshatra, or weekday and tithi, that the classical literature singles out as strongly auspicious or strongly adverse.

Every moment, not just a birth, has a rising sign — the point of the zodiac crossing the eastern horizon right then. The muhurta lagna reads that momentary ascendant the same way a natal chart reads a birth ascendant, and is the one panchanga-adjacent factor that needs a location to compute at all.

Gochar is the classical study of where each graha is transiting right now, read against the birth chart's Moon sign rather than against the calendar. Vyoma applies it selectively: which grahas matter, and in which houses, depends on what the moment is being used for.

Rahu Kalam, Yamaganda and Gulika Kalam are three daily windows, each one eighth of the daylight hours, that the weekday assigns to different segments of the day and that muhurta practice classically avoids for starting new undertakings.

A purpose profile takes the same panchanga, chandra bala and gochar readings used everywhere else and adds a small set of extra checks specific to one kind of undertaking — a journey, a signing, a wedding — on top of the general-purpose score, rather than replacing it.
