Punarvasu breaks into two words meaning again and good, or again and dwelling. Both point the same way. Something was had, something was lost, and this star describes the part where it comes back.
Punarvasu is the birth nakshatra of Lord Rama. That fits the star exactly. His story is one long exile followed by a return, and what comes back at the end is not quite what left. If you were born under Punarvasu, you share a birth star with him, and Ram Navami is celebrated with this nakshatra in mind.
In Hindu mythology, Aditi is the mother of the Adityas, the solar gods, and her name means boundless or unbounded. She is the space in which things can exist. That is the mechanism behind the restoration here: there is room to begin again, even when the broken thing cannot be repaired exactly.
The bow and quiver finish the picture. An arrow once fired is gone, and the quiver holds more. A person who has spent an attempt is not out of attempts. Its shakti (the special power a nakshatra carries) is regaining what was lost.
Punarvasu is known for resilience, teaching and a philosophical outlook. Natives tend to be the ones who recover, retake the exam, restart the business, and make everyone around them believe that a bad year is not the whole story.
