tataś ca paugaṇḍa-vayaḥ-śrītau vraje
babhūvatus tau paśu-pāla-sammatau
gāś cārayantau sakhibhiḥ samaṁ padair
vṛndāvanaṁ puṇyam atīva cakratuḥ
Śukadeva Gosvāmī said: When Lord Rāma and Lord Kṛṣṇa attained the age of paugaṇḍa [six to ten] while living in Vṛndāvana, 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 Vṛndāvana most auspicious by imprinting upon it the marks of Their lotus feet.
