A sannyasi is dutybound to take all these risks without fear, and the most typical sannyasi of the present age is Lord Caitanya, who travelled in the same manner through the central Indian jungles, enlightening even the tigers, bears, snakes, deers, elephants and many other jungle animals. In this age of Kali, sannyasa is forbidden for ordinary men.
One who changes his dress to make propaganda is a different man from the original ideal sannyasi. One should, however, take the vow to stop social intercourse completely and devote life exclusively to the service of the Lord. The change of dress is only a formality. Lord Caitanya did not accept the name of a sannyasi, and in this age of Kali the so-called sannyasis should not change their former names, following in the footsteps of Lord Caitanya. In this age devotional service of hearing and repeating the holy glories of the Lord is strongly recommended. SB 1.6.13
