“vārāṇasī paryanta svacchande yāibā pathe āge sāvadhāne yāibā kṣatriyādi-sāthe
“You may go as far as Vārāṇasī without encountering disturbances, but beyond Vārāṇasī you should be very careful to travel on the path in the company of the kṣatriyas.
Purport
In those days the path from Vārāṇasī to Vṛndāvana was infested with robbers, and therefore there were kṣatriyas to protect travelers.
