Mbh 12.154.2a

"'Bhishma said, "In this connection is cited, O chief of the Bharatas, the old story of the discourse between Salmali and Pavana. There was a lordly (Salmali) tree on one of the heights of Himavat. Having grown for many centuries, he had spread out his branches wide around. His trunk also was huge and his twigs and leaves were innumerable. Under his shade toil-worn elephants in rut, bathed in sweat, used to rest, and many animals of other species also. The girth of his trunk was four hundred cubits, and dense was the shade of his branches and leaves. Loaded with flowers and fruits, it was the abode of innumerable parrots, male and female. In travelling along their routes, caravans of merchants and traders, and ascetics, residing in the woods, used to rest under the shade of that delightful monarch of the forest. One day, the sage Narada, O bull of Bharata's race, seeing the wide-extending and innumerable branches of that tree and the circumference of his trunk, approached and addressed him, saying, 'O thou art delightful! O thou art charming! O foremost of trees, O Salmali, I am always delighted at thy sight! O charming tree, delightful birds of diverse kinds, and elephants and other animals, cheerfully live on thy branches and under their shade. Thy branches, O wide-branched monarch of the forest, and thy trunk are gigantic. I never see any of them broken by the god of the wind. Is it, O child, the case that Pavana is pleased with thee and is thy friend so that he protects thee always in these woods? The illustrious Pavana possessed of great speed and force moveth from their sites the tallest and strongest trees, and even mountain summits. That sacred bearer of perfumes, blowing (when he wills) drieth up rivers and lakes and seas, including the very nether region. Without doubt, Pavana protects thee through friendship. It is for this reason that, though possessed of innumerable branches, thou art still graced with leaves and flowers.
