"There were various trees and creepers on all sides of the lake, and there were mad bumblebees humming all about them. The trees appeared to be very jolly due to the sweet humming of the bumblebees, and the saffron, which was contained in the lotus flowers, was being thrown into the air. These all created such an atmosphere that it appeared as though a festival were taking place there.
Purport: "Trees and creepers are also different types of living beings. When bumblebees come upon trees and creepers to collect honey, certainly such plants become very happy. On such an occasion the wind also takes advantage of the situation by throwing pollen or saffron contained in the lotus flowers. All this combines with the sweet vibration created by the swans and the calm of the water.
Srimad-Bhagavatam 4:24:22 Purport
"Accompanied by the cowherd boys and Balarama, Krsna brought forward the cows and played on His flute through the forest of Vrndavana, which was full of flowers, vegetables, and pasturing grass. The Vrndavana forest was as sanctified as the clear mind of a devotee and was full of bees, flowers and fruits. There were chirping birds and clear water lakes with waters that could relieve one of all fatigue. Sweet flavored breezes blew always, refreshing the mind and body. Krsna, with His friends and Balarama, entered the forest and, seeing the favorable situation, enjoyed the atmosphere to the fullest extent. Krsna saw all the trees, overloaded with fruits and fresh twigs, coming down to touch the ground as if welcoming Him by touching His lotus feet. He was very pleased by the behavior of the trees, fruits and flowers, and He began to smile, realizing their desires.
Krsna then spoke to His elder brother Balarama as follows: "My dear brother, You are superior to all of us, and Your lotus feet are worshiped by the demigods. Just see how these trees, full with fruits, have bent down to worship Your lotus feet. It appears that they are trying to get out of the darkness of being obliged to accept the form of trees. Actually, the trees born in the land of Vrndavana are not ordinary living entities. Having held the impersonal point of view in their past lives, they are now put into this stationary condition of life, but now they have the opportunity of seeing You in Vrndavana, and they are praying for further advancement in spiritual life through Your personal association. Generally the trees are living entities in the mode of darkness. The impersonalist philosophers are in that darkness, but they eradicate it by taking full advantage of Your presence.
"It is quite natural for these Vrndavana inhabitants to thus receive a great personality like You. The herbs, creepers and plants are also so fortunate to touch Your lotus feet. And by Your touching the twigs with Your hands, these small plants are also made glorious. As for the hills and the rivers, they too are now glorious because You are glancing at them. Above all, the damsels of Vraja, the gopis, attracted by Your beauty, are the most glorious, because You embrace them with Your strong arms."
Krsna Book, Chapter 15
"Govinda resides eternally in Vrndavana. In the spiritual world of Vrndavana the buildings are made of touchstone, the cows are known as surabhi cows, givers of abundant milk, and the trees are known as wish-fulfilling trees, for they yield whatever one desires. In Vrndavana Krsna herds the surabhi cows, and He is worshiped by hundreds and thousands of gopis, cowherd girls, who are all goddesses of fortune. When Krsna descends to the material world, this same Vrndavana descends, just as an entourage accompanies an important personage. Because when Krsna comes His land also comes, Vrndavana is not considered to exist in the material world. Therefore devotees take shelter of the Vrndavana in India, for it is considered to be a replica of the original Vrndavana. Although one may complain that no kalpa-vrksa, wish-fulfilling trees, exist there, when the Gosvamis were there, kalpa-vrksa were present. It is not that one can simply go to such a tree and make demands; one must first become a devotee. The Gosvamis would live under a tree for one night only, and the trees would satisfy all their desires. For the common man this may all seem very wonderful, but as one makes progress in devotional service, all this can be realized."
