Śukadeva Gosvāmī said: When Lord Rāma and Lord Krishna attained the age of pauganda [six to ten] while living in Vrindāvana, the cowherd men allowed Them to take up the task of tending the cows. Engaging thus in the company of Their friends, the two boys rendered the land of Vrindāvana most auspicious by imprinting upon it the marks of Their lotus feet.

Lord Krishna wanted to encourage His cowherd boyfriends, who had been swallowed by Aghāsura and then stolen by Lord Brahmā. Therefore the Lord decided to bring them into the palm-tree forest called Tālavana, where there were many delicious ripe fruits. Since Lord Krishna’s spiritual body had apparently grown slightly in age and strength, the senior men of Vrindāvana, headed by Nanda Mahārāja, decided to promote Krishna from the task of herding calves to the status of a regular cowherd boy. He would now take care of the full-grown cows, bulls and oxen. Out of great affection, Nanda Mahārāja had previously considered Krishna too small and immature to take care of full-grown cows and bulls. It is stated in the Kārttika-māhātmya section of the Padma Purāna:
smritā gopāshtamī budhaih
tad-dinād vāsudevo ’bhūd
gopah pūrvam tu vatsapah
“The eighth lunar day of the bright fortnight of the month of Kārttika is known by authorities as Gopāshtamī. From that day, Lord Vāsudeva served as a cowherd, whereas previously He had tended the calves.”
The word padaih indicates that Lord Krishna blessed the earth by walking on her surface with His lotus feet. The Lord wore no shoes or other footgear but walked barefoot in the forest, giving great anxiety to the girls of Vrindāvana, who feared that His soft lotus feet would be injured.
