Sometimes on the street some outsider, seeing you, they chant Hare Krsna only by the symbolic, sanketya. Because they see: "They have got tilaka, kanthi." Therefore these things are required. Don't become immediately paramahamsa — no tilaka, no kanthi and no bead bag. This is not good. Sanketya, so that others may understand, "Here is a Vaisnava. Here is a Krsna devotee." And if he is simple, he'll chant "Hare Krsna." This chance should be given. Therefore it is necessary, how people can utter. That chanting may save him from the greatest danger.
