Sanskrit:

वहन्तो वाह्यमानाश्च चारयन्तश्च गोधनम् ।भाण्डीरकं नाम वटं जग्मु: कृष्णपुरोगमा: ॥ २२ ॥

ITRANS:

vahanto vāhyamānāś cacārayantaś ca go-dhanambhāṇḍīrakaṁ nāma vaṭaṁjagmuḥ kṛṣṇa-purogamāḥ

Translation:

Thus carrying and being carried by one another, and at the same time tending the cows, the boys followed Kṛṣṇa to a banyan tree known as Bhāṇḍīraka.

Purport:

Śrīla Sanātana Gosvāmī quotes the following verses from Śrī Harivaṁśa (Viṣṇu-parva 11.18-22), which describe the banyan tree: “They saw that best of all trees, which had many long branches. With its dense covering of leaves, it resembled a cloud sitting on the earth. Indeed, its form was so large that it appeared like a mountain covering half the sky. Many birds with charming blue wings frequented that great tree, whose dense fruits and leaves made it seem like a cloud accompanied by a rainbow or like a house decorated with creepers and flowers. It spread its broad roots downward and carried upon itself the sanctified clouds. That banyan tree was like the lordly master of all other trees in that vicinity, as it performed the all-auspicious functions of warding off the rain and the heat of the sun. Such was the appearance of that nyagrodha tree known as Bhāṇḍīra, which seemed just like the peak of a great mountain.”
