There are two “competing” Devis.
One is the Devi Who holds a Mirror in Her hand. Her stories fill us with Wonder. As She tells us Her stories that take us to Other Worlds, She enhances the flavor by visions, holding up a Mirror before us, we look into the Mirror and as we stare deep into the Mirror which if we directly look into the oiled metal we see our face.
But She turns it slightly. Very slightly. Then we see a gray matter that turns silver, but then. A movement is seen in the Mirror. At first it could be a snake. But it is like smoke.
Indeed, it is a Smoke that moves and twists across the Mirror. We look more carefully.
Surely this Smoke is alive. Now it becomes many things. We see the motion in the Mirror, and it is alive, and soon is seen many things.
The Smoke is not in the Mirror, however. It is behind our head. There is an incense burner, with coals, and a powdered incense made from dried scorpions who never die even as they burn. An attractive smell comes from them.
But we cannot stop looking into the Mirror.
There is another Devi, she is nearby. She is the Smoke Thief.
This Devi steals the smoke. She comes very quietly, and stealthily comes up to the incense burner. She is also behind our head. She holds a cup upside down over the Smoke. All the smoke enters the cup and is gone.
Now we see nothing in the Mirror. We say to the Devi, where is the cobra I was observing in the Mirror? I could not take my eyes off its swaying and dance. Devi says, oh, that cobra was not real, it was only Smoke in My Mirrors. But then She turns the Mirror directly to our face, and we see our face. Time had passed. Who is that we ask?
You do not know, asks Devi? It is you. You have stared at the Cobra of Smoke for some time. Time passed, you do not recognize yourself it has been a long time. But now look.
Then She turns the Mirror a bit more the other way.
And there is the Smoke Thief Goddess. She is smiling, holding Her cup still upside down. We ask, Who is She? But we already know.
In this cup is all of your dreams, She says. The visions of a long time.
She turns the cup over. And the entire chamber is filled with smoke.
You cannot find your way. But it clears. And She is still standing there.
Anyway, someone told me this. But that person is strange. Who are these two Devis? The consorts of Surya, Saranyu and Chhaya. Saranyu is the Devi of Clouds and Smoke, Her Son is Yama the God of Death. And there is Chhaya, the Devi of Shadow. She holds a Mirror, and Her Son is Shani the Planet Saturn Who mounts the Raven.
