Almost every Tirthankara is named for something that happened during his mother’s pregnancy. Sumatinatha is named for something his mother did. It is the one naming episode in the twenty-four where the woman is the agent rather than the setting, and it is worth the page on its own.
The Five Kalyanakas
| Kalyanaka | Tithi | Nakshatra |
|---|---|---|
| Chyavana (conception) | Shravana Shukla 2 | Magha |
| Janma (birth) | Vaishakha Shukla 8 | Magha |
| Diksha (renunciation) | Vaishakha Shukla 9 | Magha |
| Kevala Jnana (omniscience) | Chaitra Shukla 11 | Magha |
| Nirvana (liberation) | Chaitra Shukla 9 | Punarvasu (shifts) |
Every date in his table is a bright-fortnight date, which means the purnimanta and amanta reckonings name all five months the same way and no translation between panchangs is needed. He is one of only six of the twenty-four for whom that is true. Where you do see disagreement about his dates, it is not a calendar artefact, and the next section is about where it comes from.
His first four kalyanakas fall in Magha. Only the nirvana moves, to Punarvasu, and that particular move is the most awkward in the whole set.
The Star That Runs Backwards
Most of the ten nirvana shifts go forward. Shreyansanatha moves from Shravana to Dhanishtha, one step on. Vimalanatha moves from Uttara Bhadrapada to Revati, one step on. Vasupujya moves from Shatabhisha to Uttara Bhadrapada, two steps on. The pattern is so consistent that a reader could be forgiven for assuming it is a rule.
Sumatinatha’s does the opposite. Magha is the tenth nakshatra. Punarvasu is the seventh. His nirvana star sits three places earlier in the sequence than his birth star, and nothing else in the set moves that direction by that much.
Johnson’s translation of Hemachandra is unambiguous about it. A number of modern tables quietly disagree, and print something forward-moving instead, or simply repeat Magha in the fifth row. We print what the text says. If a manuscript reading supports the modern tables we would like to see it, but we are not going to smooth a transmitted value because it spoils a pattern, and a pattern that ten cases nearly obey is not a rule that the eleventh has broken.
The date itself is confirmed outside Hemachandra: Chaitra Shukla 9, in Punarvasu, at Shikharji, after a final fast.
His Mother’s Judgment
The name is su-mati, good mind, sound judgment. The tradition does not attach it to a dream.
Hemachandra says the father gave the child the name because of the sharpening of the queen’s intellect during the pregnancy, and the reference works preserve the episode that demonstrated it. An old brahmin died leaving two wives. Both claimed the one surviving son. The dispute came to Queen Mangala, who ruled that the child should be divided between them, at which one of the two gave up her claim rather than see it done, and the case settled itself.
Anyone raised on the Hebrew Bible will recognise the shape of it. The judgment of Solomon in 1 Kings turns on exactly the same device and exactly the same reveal. We are not going to claim one borrowed from the other, because we do not know and neither does anyone else; wisdom-tale motifs travelled the trade routes freely in both directions for two thousand years. What we can say is that the Jain telling puts the judgment in a woman’s mouth, credits it to a pregnancy rather than to a king’s wit, and names a Tirthankara after it.
Set it against the other naming episodes on this site and the difference is sharp. Anantanatha is named for wars his father won. Naminatha for enemies who bowed to his father. Shantinatha for an epidemic that lifted. In each of those the mother is where the event happens. Here she is the one who acts.
A Bird That Does Not Survive Translation
The lanchhana on this site is the krauncha bird, and we keep the Sanskrit deliberately, because English has no settled equivalent and every attempt to supply one has produced a different animal.
Krauncha is glossed as heron, as demoiselle crane, and as curlew. All three are long-legged waterbirds and none of them is the same bird. English-language Jain lists then compound the problem by offering red goose, goose, swan and koka-bird. Some of that is genuine variation in the Digambara reading, which gives crane or koka; most of it is translators reaching for a familiar name.
The two sects are not far apart here. Shvetambara sources give the krauncha; Digambara sources give the crane or the koka-bird, which are the same family of guess at the same Sanskrit word. This is not a sectarian dispute like Anantanatha’s falcon and porcupine. It is a translation problem, and printing “curlew” as though it were settled is the mistake.
The iconographic literature adds a reading worth knowing. Whichever waterbird it is, the bird is associated with discernment, and in the wider Indian tradition the hamsa is the vehicle of Sarasvati, goddess of intelligence. On that reading the emblem restates the name: sumati, good judgment, carved as the bird that separates what it wants from what it does not. We record it as an interpretation of the iconography, which is what it is, not as a fact about the fifth Tirthankara.
Ayodhya, and What Actually Marks the Spot
Ayodhya is the birthplace of five Tirthankaras in Jain reckoning, more than any other city: Rishabhanatha the first, Ajitanatha the second, Abhinandananatha the fourth, Sumatinatha the fifth, and Anantanatha the fourteenth. Four of the five belong to the opening stretch of the cycle, and Anantanatha comes back to it much later.
Local Jain tradition marks the birthplaces of Sumatinatha and Anantanatha together at a temple in Mohalla Mondhiana near Rajghat. That is a devotional identification maintained by the community rather than an archaeological one, and it should be described as such; the Jain sites of Ayodhya have not been excavated to the point where any of the five can be independently fixed.
His liberation was at Shikharji, the ridge in Jharkhand where twenty of the twenty-four were released. His tonk there enshrines his footprints, as each of the twenty has.
Attendants, and Names That Move
His yaksha is Tumburu in both traditions, which is more agreement than most of the twenty-four get. The yakshi divides: Mahakali in Shvetambara sources, Purushadatta in Digambara ones. Some popular tables print Purushadatta as the yaksha, which is a straightforward error of column.
His father’s name moves as well. Shvetambara sources give Megha, Digambara sources Meghaprabha, and a third reading, the one this site prints, gives Megharatha. His mother is Mangala throughout, which is fitting for the one Tirthankara whose name is really hers.
He reached omniscience under a priyangu tree, and Hemachandra puts his height at three hundred bows. Both figures belong to the cosmological register of the text rather than to anything measurable, and we report them as the text’s own numbers.

Magha, and a Star Held by One
Magha is the tenth nakshatra, at the head of Simha, and among the twenty-four it belongs to Sumatinatha alone. No other Tirthankara’s kalyanaka days overlap with yours on this basis, which makes the kinship exclusive rather than shared.
Exclusive is not the same as significant, and we should be plain about the difference. What a shared janma nakshatra gives you is a set of dates you can observe, a life you can read and an image you can stand in front of. It does not give you a temperament, a compatibility or a forecast, and no classical Jain source has ever suggested it does. The full argument is at why no honest Tirthankara horoscope can exist.
Our free kundali tool computes your janma nakshatra and names the Tirthankaras who share it. The cross-verified table for all twenty-four is at the birth stars of the 24 Tirthankaras.
