The Vaisnavas, with tilaka, with kunti, with chanting beads, as soon as you see… And practically you know. As soon as they see these Hare Krsna movement people, they also chant, "Hare Krsna," giving a chance to the others. The dress is also required. You should be always equipped with tilaka, kunti, and sikha, sutra. Then, as soon as a common man sees, "Oh, here is a Hare Krsna man. Hare Krsna," he'll chant. Automatically you give a chance to chant Hare Krsna.

So this is required. The foolish rascals, they say that "What is the necessity of this, that?" No. This is necessity. You must always remain dressed like a Vaisnava. That is necessity.
