The vānaras searching for Sītā had reached the point where they believed the search had failed.
They had no destination left to follow.
Then they met an old bird who could no longer fly.
His name was Sampāti. He was the elder brother of Jaṭāyu.
When the vānaras spoke of Jaṭāyu, Sampāti learned what had happened to his younger brother: Jaṭāyu had fought Rāvaṇa while Sītā was being carried away and had died after giving Rāma the direction in which Rāvaṇa had gone.
Sampāti grieved, but he also had to admit what age and injury had done to him. He had no wings with which to pursue his brother's enemy.
He told the vānaras how the wings had been lost.
Long before, the two brothers had flown upward toward the sun, competing in their strength. When the heat overwhelmed Jaṭāyu, Sampāti spread his own wings over his younger brother to shield him.
Jaṭāyu survived the heat. Sampāti's wings were burned, and he fell to the Vindhya mountain.
Now the searchers asked the question that mattered: did he know where Rāvaṇa had taken Sītā?
Sampāti answered with extraordinary precision about what he could and could not offer.
His wings were burned. His strength was diminished.
The best help I can give Rāma now is through my words, he said in the sense of the Sanskrit passage.
Those words gave the search a destination.
Sampāti identified Laṅkā across the ocean and told them that Sītā was there.
He described the direction and distance well enough that the vānaras who had been preparing to give up now knew where their effort had to go.
The strongest jumpers in the world had finally been told where to jump.
Sampāti then asked the vānaras to carry him to the sea so that he could offer water for Jaṭāyu.
They carried the wingless bird to the shore, and afterwards brought him back.
The later part of this sequence gives another layer to his history.
A sage named Niśākara had once told Sampāti that a time would come when Rāma's messengers would arrive searching for Sītā. Sampāti's role would be to give them the news they needed.
The prophecy also said that his wings would return.
Sampāti had waited through the years with that promise in mind.
After he had given the vānaras the information and finished telling his history, new wings appeared.
Red feathers grew. His strength returned enough for him to rise again.
Then he flew away, while the vānaras turned toward the southern journey and the ocean that still had to be crossed.
Not every manuscript preserves the later chapters in the same form. Some received versions include the prophecy and restored wings; others do not.
That difference does not change the heart of Sampāti's help here: he gives the searchers the direction to Laṅkā while he is still wingless.
The part common to the story's heart is simpler.
Sampāti does not wait until his old physical power returns before he becomes useful.
He helps while still wingless.
Knowledge, memory, sight and words are enough to change what the searchers can do next.
The received continuation also explains how Sampāti knew so much after years on the mountain. His son had been bringing him food, and in the extended account Sampāti tells the vānaras what had been reported about Rāvaṇa carrying Sītā through the sky. That material belongs to the same textually debated stretch as the prophecy and restored wings.
Niśākara's prophecy is unusually specific about Sampāti's waiting. The sage tells him that Rāma's messengers will one day come seeking Sītā and that Sampāti must remain alive long enough to tell them what he knows. His old age is therefore not empty delay inside this received version; it carries a task he cannot perform until the searchers arrive.
Sampāti's wings return later; the help that saves the search comes first, from what he still knows.
