nalini nalini ca prag
dvarav ekatra nirmite
visayam yati saurabham
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Similarly in the east there were two sets of gates named Nalini and Nalini, and these were also constructed in one place. Through these gates the King, accompanied by a friend named Avadhuta, used to go to the city of Saurabha.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The two gates named Nalini and Nalini are the two nostrils. The living entity enjoys these two gates with the help of different avadhutas, or airs, which constitute the breathing process. Through these gates the living entity goes to the town of Saurabha, or aroma. In other words, the nostrils, with the help of their friend the air, enjoy various aromas in the material world. Nalini and Nalini are the pipes of the nostrils, through which one inhales and exhales, enjoying the aroma of sense pleasure.
