By following His footsteps, you can approach Nityananda Prabhu. Nityananda Prabhu approached Jagai and Madhai at the risk of being personally injured and still He definitely delivered them. The world is full of Jagais and Madhais; namely drunkards, women-hunters, meat eaters and gamblers, and we will have to approach them at the risk of insult, injury and similar other rewards. To face such reverse conditions of life and to suffer thereby the results of actions is considered as the greatest penance and austerity in the matter of spiritual advancement of life.
To sit down in a corner without preaching risk and to make a show of chanting Hare Krishna Mantra is condemned by my Spiritual Master and He has written a very nice song in this connection. The substance is that to become very dear to Krishna or Balarama or in other words to Lord Caitanya and Nityananda is to take the task of preaching work very seriously at all risk. Please always remember this and you will be successful.
