Siddhānta — the theory
A chart can be asked how long. It is the gravest question the science permits, and the tradition answers it with unusual care — never with a date, but with a span: one of five received measures, read from the balance of a few decisive placements. Āyurdāya is a tendency to be weighed, and a life to be protected — not a term to be pronounced.
To read the span, the tradition first names the three points of life — the prāṇa-bindu. For one soul the thread of life is held in the body, and read from the Lagna; for another in the living awareness, the Sun; for a third in the tie of body to mind, the Moon. Danger gathers where cruel planets converge — by transit and by progression — upon whichever of the three holds the point of life. When all three are struck at once, the reading is certain; when any two are struck, it is grave.
Then it weighs the two lords of life. The lagna-lord rules the vessel itself; the eighth-lord rules the āyuḥsthāna, the house of the term of life. Take whichever of the two is the stronger: set in an angle (1·4·7·10) it reads long; in a succedent house (2·5·8·11) it reads middling; in a cadent house (3·6·9·12) it reads short — and its dignity is weighed the same way. Over both stands Śani, the āyuḥkāraka, the very significator of long life, lending its steadiness when well seated. No single rule is read alone: gather them all, find the chart's strongest planet, and let the synthesis speak.
The gravest reading of all — bālāriṣṭa, a fragile beginning — is the one the tradition hedges most heavily with parihāras. A benefic — Guru or Śukra — in a trine to the lagna or the Moon; a lagna-lord exalted or in its own sign; a full Moon flanked by benefics — any one of these lifts it. The grave reading is a warning to protect, never a sentence to pronounce.
The West keeps no five-fold reckoning of the span. It reads vitality and its threats: the 1st house and its ruler for the body's stamina, the 6th and 8th for illness and crisis, Saturn for endurance and the slow limit, the Sun for the life-force itself. It counts the hazards to a life — it does not name its length.
Jyotiṣa builds the span outright. It balances the lagna-lord against the eighth-lord, sets Śani as the āyuḥkāraka, and names the measure — alpa, madhya, dīrgha — from the strongest planet in the chart. And it never speaks that measure without, in the same breath, the parihāra that would guard the life.
Hold both eyes together. The West audits the hazards; Jyotiṣa reads the span and its protections. Neither is a death-clock — one names what threatens a life, the other how long the chart tends to hold it, and both fall silent before the soul that is not its body.
The tradition guards one truth above the whole reckoning: death-fear is itself the death. A soul steady in the Self does not die — it puts off a garment. To presume to time the passing of such a one is reckless. The science was given for self-knowledge, and for the immortality that self-knowledge is — not for prophecy. Read a span to cherish a life, and to protect the fragile. Never to frighten.
The bones of this reading are frame-free. A lord's house from the lagna, the angle / succedent / cadent class, the seats of the three prāṇa-bindu — these are whole-sign counts, and the ayanāṁśa moves them not at all, exactly as it leaves the aspects untouched. Only the lord's dignity is sign-bound — the Vedic layer. So Arka weighs the house-balance first, and reads the dignity within its own zodiac.
No single āyurdāya yoga stands alone: gather every one, find the chart's strongest planet, and reckon the span from it — so the tradition insists, and so must the reader. Śani is the āyuḥkāraka. And the whole art is held beneath one rule above the rest: that a birth-affliction is a tendency to be eased, and that the reckoning of a life's term is, in the end, an act of care — not calculation.
A dispute the lineage settled long ago — kept here in Arka's own voice.
The question is not how long but how held. Five spans, three points of life, two lords and their cancellations — the chart names a tendency, and the reader answers it with protection. Read the span to guard the flame, never to name its going-out.
Jyotiṣa builds the span outright. It balances the lagna-lord against the eighth-lord, sets Śani as the āyuḥkāraka, and names the measure — alpa, madhya, dīrgha — from the strongest planet in the chart. And it never speaks that measure without, in the same breath, the parihāra that would guard the life.

The Scales of Life आयुस्तुला
Set the balance yourself. Where does the stronger āyu-lord sit; what is its dignity; does a benefic guard the lagna; is Śani well-seated; and how many of the three points of life are struck? Watch the span the tradition would read — and, where the gravest reading appears, watch a single parihāra lift it.

Prayoga — read the span
Each life below carries the marks of one span. Read the vignette and name it. The reveal names the class — and, where the reading was grave, the parihāra that held it.
{{ caseText }}
{{ caseWhy }}
Take a chart you know well — never a stranger's, and never to frighten. Find its two āyu-lords and the stronger of them; note its seat and dignity, and where Śani sits. Then ask the harder question: what protects this life — which benefic, which trine, which strong lord? Write the span you would read, and the parihāra you would name in the same breath.
Siddhi — read the span unaided.
A placement is named. One line reads it as the tradition would — the others belong to a different span, or misread this one.
