Canto 10 Chapter 15 Text 1
tatas ca pauganda-vayah-sritau vraje
babhuvatus tau pasu-pala-sammatau
gas carayantau sakhibhih samam padair
vrndavanam punyam ativa cakratuh
Sukadeva Gosvami said: When Lord Rama and Lord Krsna attained the age of pauganda [six to ten] while living in Vrndavana, 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 Vrndavana most auspicious by imprinting upon it the marks of Their lotus feet.
