CC Antya 13.34

“vārāṇasī paryanta svacchande yāibā pathe
āge sāvadhāne yāibā kṣatriyādi-sāthe
Word for word: 
vārāṇasī paryanta — up to Vārāṇasī; svacchande — without disturbance; yāibā pathe — you can go on the path; āge — after that; sāvadhāne — with great care; yāibā — you should go; kṣatriya-ādi-sāthe — with the kṣatriyas.
Translation: 
“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.
