Revati closes the circle. It is the last of the twenty seven, sitting at the end of Pisces, and everything about it concerns completion: finishing well, arriving safely, handing something over intact.
In Hindu mythology, Pushan is a solar deity who protects travellers, guides herds and makes sure people reach the place where they can be fed. He knows the roads. He is invoked on journeys and at funerals, because both are passages that need someone who knows the way.
Its shakti (the special power a nakshatra carries) is nourishment: making sure that whoever is travelling actually gets sustained along the way.
The fish is the main symbol, joined in some accounts by a drum. A fish moves easily through water that would drown anything else, which is a fair description of how Revati natives handle emotional situations that overwhelm other people.
Revati is known for kindness, imagination and looking after animals and children. Natives are the ones who notice who has been left out, who feed the street dogs, who help the confused person at the railway station. It is the gentlest of the twenty seven by reputation, and mostly it earns that.
