The Krsna consciousness movement is especially meant for creating an atmosphere in which people can take to the chanting of the Hare Krsna mantra. One must begin with faith, and when this faith is increased by chanting, a person can become a member of the Society. We are sending sankirtana parties all over the world, and they are experiencing that even in the remotest part of the world, where there is no knowledge of Krsna, the Hare Krsna maha-mantra attracts thousands of men to our camp. In some areas, people begin to imitate the devotees by shaving their heads and chanting the Hare Krsna maha-mantra, only a few days after hearing the mantra. This may be imitative, but imitation of a good thing is desired. Some imitators gradually become interested in being initiated by the spiritual master and offer themselves for initiation.
