Methodology · Nivas & Shool

How Nivas & Shool are determined

Where the sacred fire, Shiva and the oblation “reside” today, and which way the Kumbha points — the residence (nivas) and thorn (shool) indicators the panchang weighs for havan, puja and travel.

What they are

Residence (nivas) and thorn (shool)

The nivas indicators name where a deity or element “resides” today — the residence decides whether the day favours a fire ritual or a Shiva worship. The shool indicators name a direction to weigh before setting out. Together they are the classical checklist consulted before havan, rudrabhishek and travel.

Some depend on the tithi (and so change at the tithi turn), others on the nakshatra — we compute each from the true Drik-Ganita panchang and show its turnover time where it has one.

Agnivasa

Where Agni resides

The residence of the sacred fire, from the tithi and the weekday. Only when Agni is on the Earth (Prithvi) is a havan fully fruitful.

Agnivasa is found from the tithi number (1–30) and the weekday:

Take the day-number

day = the weekday counted Sunday = 1 … Saturday = 7.

Add and reduce

remainder = (tithi + 1 + day) mod 4.

Read the residence

remainder 0 or 3 → Prithvi (Earth); 1 → Akasha (Sky); 2 → Patala (the nadir).

Agni resides in	Reading
Prithvi (Earth)	Auspicious — the only residence fit for a fruitful havan; bestows comfort.
Akasha (Sky)	Inauspicious for fire ritual.
Patala (Nadir)	Inauspicious — said to destroy the fruit of the offering.

Shivavasa

Where Shiva resides

From the tithi alone (the rudrabhisheka method). Rudrabhishek is offered when Shiva is on Kailasha, with Gauri, or on Nandi.

Shivavasa is taken from the tithi as remainder = (tithi × 2 + 5) mod 7, which maps to one of seven residences. Three are auspicious for Rudrabhishek; four are avoided.

Shiva resides	Result
On Kailasha	Happiness — auspicious.
With Gauri	Domestic happiness & prosperity — auspicious.
On Nandi (Vrishabha)	Success — auspicious.
In Sabha (assembly)	Grief — avoid.
In Krida (at play)	Difficulty — avoid.
In Bhojana (dining)	Trouble — avoid.
In Shmashana	The cremation ground — strongly inauspicious.

Because both Agnivasa and Shivavasa are read from the tithi, they change at the tithi turn — so the panchang shows the value that holds now, its “until” time, and the residence the next tithi brings.

Homahuti & Kumbha Chakra

The nakshatra indicators

Two more readings taken from the day’s nakshatra — one for the oblation, one for direction.

Homahuti

The graha that “receives” the fire oblation today, cycling through the nine grahas by nakshatra. Mercury, Jupiter and Venus are the auspicious recipients; the rest are held inauspicious for homa.

Kumbha Chakra

The day’s nakshatra places the ritual “pot” toward a direction or part. South, West, and the Bottom / Throat placements are auspicious; East, North and the Womb placement are avoided for undertakings.

The direction vasas

The Nivas & Shool panel also carries Disha Shool, Rahu Vasa and Chandra Vasa — the pure direction indicators. Their weekday and Moon-rashi tables are covered in how Disha Shool is determined.
