Sāvitrī knew the date.
Before she married Satyavān, the sage Nārada had said that Satyavān possessed the qualities people praised in him — and that he would die one year from that day.
Sāvitrī was urged to choose someone else. She did not. She married Satyavān, went to live with him and his parents in the forest, and remembered the prediction.
As the appointed day approached, she observed a severe vow.
On that day Satyavān went into the forest to gather fruit and cut wood. Sāvitrī went with him.
While working, he began to perspire. His head hurt badly and his limbs weakened. He told Sāvitrī that he could no longer stand.
She sat on the ground and placed his head in her lap.
Satyavān died there.
Then Sāvitrī saw Yama.
Yama had come personally for Satyavān. He took the prince's life and began travelling south.
Sāvitrī followed.
Yama told her to turn back. Her duties to her husband had reached their end; she should return and perform the rites.
Sāvitrī kept walking.
She spoke about the path people share, about duty, and about how even walking seven steps together is said to create a bond of friendship.
Yama was pleased by her words.
Ask for a boon, he said. Anything except Satyavān's life.
Sāvitrī asked that her blind father-in-law regain his sight and strength.
Granted. Now turn back.
She continued.
She spoke again, this time about the value of keeping company with the good.
Yama offered a second boon.
Sāvitrī asked that her father-in-law regain the kingdom he had lost and remain firm in his duties.
Granted. Go back.
Still she walked.
She spoke about justice, mercy and the way good people protect even those who come to them seeking shelter.
Yama offered another boon.
Sāvitrī asked that her own father, who had no sons, receive a hundred sons.
Granted. You have come far enough.
Sāvitrī said that beside her husband she did not notice how long the road had become.
Again she spoke about trust in the righteous.
Yama offered a fourth boon, still excluding Satyavān's life.
Sāvitrī asked for a hundred sons for herself and Satyavān.
Yama granted it.
Sāvitrī continued the conversation until Yama, increasingly pleased by what she said, offered an incomparable boon.
Now she pointed to the promise already made.
How could she have a hundred sons with Satyavān if Satyavān remained dead?
She asked directly for his life so that Yama's own words could stand true.
Yama released Satyavān and promised him a long life.
Then Yama departed.
Sāvitrī returned to the place where her husband's body lay and again placed his head in her lap.
Satyavān woke as though from deep sleep. He remembered the pain in his head and a dark, powerful figure, but not the whole journey Sāvitrī had just taken beside Yama.
The other boons also unfold: sight and kingdom return to Satyavān's father, and the promises Yama made are allowed to stand.
The story is sometimes compressed into a single clever loophole. The Mahābhārata gives something slower and more demanding.
Yama says turn back again and again. Sāvitrī does not insult him, seize what he carries or pretend death has no authority. She keeps walking, reasoning and speaking until the promises freely given along the road require a different ending.
Yama tells Sāvitrī why he has come personally instead of sending his messengers: Satyavān is so virtuous that Yama himself has come to take him. The scene therefore never turns Yama into a villain hiding from her. He tells her who he is and what he is doing.
When Satyavān wakes, night has fallen. He wants to return to his blind parents because they will be worried by his absence. Sāvitrī helps him up, takes the axe, and the two begin the journey back to the hermitage with the conversation with Yama still unknown to everyone waiting there.
Sāvitrī's strength is not one perfect sentence; it is that every time the road says stop, she still has truth left to say.
