Yogi, Avayogi & Duplicate Yogi

What are the Yogi and Avayogi?

The Yogi and Avayogi are a matched pair of chart signatures — one benefic, one malefic — derived from a single sensitive point called the Yoga Sphuta. The app labels the panel “Yogi & Avayogi” and captions it “the chart’s benefic and malefic signatures,” which is exactly how they are used: the Yogi planet is a natural well-wisher of the chart, and the Avayogi is its opposing number.

Everything in this family flows from one longitude, computed from the two luminaries. AstroShruti derives four related outputs from it: the Yogi, the Avayogi, the Duplicate Yogi, and — as a companion sensitive point — the Bhrigu Bindu.

The Yoga Sphuta and its rulers

The seed is the Yoga Sphuta, and the engine computes it as:

Yoga Sphuta = Sun longitude + Moon longitude + 93°20′

Add the Sun’s and the Moon’s sidereal longitudes together, add a fixed 93°20′, and normalise into the 0°–360° range. That single point yields two rulers, and the distinction between them is the crux of the whole topic:

So the same point is read twice — once through the sign it falls in (giving the Duplicate Yogi, also called the Dagdha Yogi) and once through the nakshatra it falls in (giving the Yogi proper). Because a sign spans more than two whole nakshatras, the sign lord and the nakshatra lord are usually different planets — which is why the app shows both as separate facts.

The Avayogi

The Avayogi is the Yogi’s malefic counterweight, and it is found from the same seed by a fixed step:

Avayogi Sphuta = Yoga Sphuta + 186°40′

Take the Yoga Sphuta, advance 186°40′ (a little past halfway round the circle), normalise, and read the nakshatra lord of that new point — that is the Avayogi planet. Because it is chained directly off the Yoga Sphuta, the Yogi and Avayogi are always computed together and always consistent with each other.

Bhrigu Bindu: the Moon–Rahu midpoint

Shown beside the Yogi points is Bhrigu Bindu, a separate sensitive longitude built not from the Sun but from the Moon and Rahu:

Bhrigu Bindu = the nearer midpoint of the Moon and Rahu

The engine measures the forward arc from the Moon to Rahu, halves it, and adds it to the Moon — landing on the midpoint that lies on the shorter side between the two. It is displayed with its sign and degree, and some schools weigh it as a focal point of destiny. That interpretive weight is classical lore; the engine only computes the position.

A structural walkthrough

Work the chain with round numbers. Suppose the Sun is at 100° and the Moon is at 200° (both sidereal longitudes):

• Yoga Sphuta = 100° + 200° + 93°20′ = 393°20′ → normalise → 33°20′. That is 3°20′ into the second sign — read its nakshatra lord for the Yogi and its sign lord for the Duplicate Yogi.
• Avayogi Sphuta = 33°20′ + 186°40′ = 220°00′. Read that point’s nakshatra lord for the Avayogi.

And for Bhrigu Bindu, if the Moon is at 200° and Rahu at 260°, the forward arc Moon→Rahu is 60°, half of it is 30°, so Bhrigu Bindu = 230°.

The walkthrough is the whole method — give the engine the Sun, Moon and Rahu and every one of these points follows mechanically, with no birth-time-of-day and no ascendant needed.

How the app shows it

In the AstroShruti app the Yogi & Avayogi atom shows four compact facts:

• Yogi — the planet (nakshatra lord of the Yoga Sphuta)
• Avayogi — the planet (nakshatra lord of the Avayogi Sphuta)
• Duplicate Yogi — the planet (sign lord of the Yoga Sphuta)
• Bhrigu Bindu — a sign and degree (the Moon–Rahu midpoint)

Note the shape of the output: the Yogi, Avayogi and Duplicate Yogi are reported as planets (they are lordships), while Bhrigu Bindu is reported as a position (a sign and degree), because it is a raw point rather than a ruler.

How to read them

• The Yogi is a friend, the Avayogi its opposite. Where the Yogi planet sits, and the dashas it rules, are classically read as supportive; the Avayogi marks the opposing current. AstroShruti names the planets and leaves this benefic/ malefic weighting to the reading — the labels “benefic” and “malefic” are the traditional framing, not a verdict the engine stamps on your chart.
• Watch for overlap. Because the Yogi is a nakshatra lord and the Duplicate Yogi is a sign lord of the same point, they can occasionally resolve to the same planet; usually they differ. Reading both tells you whether the sign and star agree on who governs the Yoga Sphuta.
• These are solar-lunar signatures. The Yoga Sphuta uses only the Sun, Moon and a fixed offset, so it does not depend on the ascendant. Twins minutes apart share the same Yogi and Avayogi.

Honest notes

• Fixed offsets, faithfully applied. The two constants — 93°20′ into the Yoga Sphuta and 186°40′ to reach the Avayogi — are applied exactly as the engine encodes them, then normalised. No rounding or sign-based shortcut is taken.
• “Nearer” midpoint for Bhrigu Bindu. The engine deliberately takes the midpoint on the shorter arc between the Moon and Rahu, not the average of the two raw numbers, so the point always lands between them on the near side.
• Positions and lordships only. As with the Upagrahas and the special lagnas, the engine reports who and where; the good/bad reading is left to interpretation.

Where it connects

The Yogi points are one of several Sun-and-Moon-derived sensitive layers, alongside the Upagrahas. Reading them turns on the Nakshatra the Yoga Sphuta falls in — the nakshatra lord is the Yogi — and on the real planetary placements you check on Grah Stithi, where you find where the Yogi and Avayogi planets actually sit.
