SB 4.25.47
khadyotavirmukhi ca prag
dvarav ekatra nirmite
vibhrajitam janapadam
yati tabhyam dyumat-sakhah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The two gates named Khadyota and Avirmukhi were situated facing the eastern side, but they were constructed in one place. Through those two gates the King used to go to the city of Vibhrajita accompanied by a friend whose name was Dyuman.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The two names Khadyota and Avirmukhi mean “glowworm” and “torchlight.” This indicates that of the two eyes, the left eye is less powerful in its ability to see. Although both eyes are constructed in one place, one is stronger than the other in the power to see. The king, or the living entity, uses these two gates to see things properly, but he cannot see unless accompanied by a friend whose name is Dyuman. This friend is the sun. Although the two eyes are situated in one place, they have no power to see without the sunlight. Vibhrajitam janapadam. If one wants to see something very clearly (vibhrajitam), he must see it with two eyes and the assistance of his friend the sunlight. Within this body everyone is a king because he uses his different gates according to his own will. Although he is very much proud of his power to see or hear, he is nonetheless dependent on the assistance of nature.
