Guest: I'm new here. I've never been here before, so forgive me if my questions are naive. But if all it requires is chanting to be pure, then why do you require musical instruments, an altar, and flowers and things of this sort?
Prabhupāda: Hm?
Viṣṇujana: If all that is required is chanting Hare Kṛṣṇa, why do we have the pictures and the clothes and the instruments and the altar and Lord Jagannātha?
Prabhupāda: Because we are personalist. We are not impersonal. This is spiritual varieties. You are talking of no varieties. Is it not? You were asking me, "Why there are so many varieties?" This is your plain question.
Guest: Not only that. Why are the heads shaved?
Prabhupāda: That is another variety. So you want variety-less. Is it not?
Guest: No. I am asking why these are necessary. Why are they necessary?
Prabhupāda: They are not necessary for a person who is advanced. But in the preliminary stage we have such necessities. This creates atmosphere, but at the same time, these varieties are not, I mean to say, material varieties. They are spiritual varieties. The place where we are trying to approach, Vaikuṇṭha, there the inhabitants are like this. They have got this tilaka, they have got... Of course, we haven't got four hands, but they have got four hands. There are two hands also. And they are dressed like this. So these things are not material varieties as much as chanting is not material vibration.
Besides that, any path you follow, you have to follow the regulative principles as they are enacted by authorities. So in our disciplic succession, previous ācāryas, they have advised that you should have your dress like this, you should have your head like this, you... So we have to follow that. Mahājano yena gataḥ sa panthāḥ (CC Madhya 17.186). Our principle is to follow the footprints of authorities. So these things are not unauthorized. These are being followed from time immemorial. This dress, this tilaka, this chanting. Everything. Just like you see the picture of Lord Caitanya, we are following the same principles. This was being enacted five hundred years ago. The same principle we are following. We are not introducing anything new. We are simply following the footprints of our predecessors. That's all.
Just like we are trying to understand Bhagavad-gītā just (as) Arjuna understood. Arjuna was direct hearer from Kṛṣṇa. So as he understood Bhagavad-gītā, we are trying to understand in that way. Kṛṣṇa said, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66), that "You give up all other engagements. You just surrender unto Me." And what we are preaching? We are also saying that "You surrender unto Kṛṣṇa." Kṛṣṇa said, "You surrender unto Me," because He is the Supreme Person Himself. And we are canvassing, "You surrender to Kṛṣṇa." So what is the difference? There is no difference. Mahājano yena gataḥ sa panthāḥ (CC Madhya 17.186). The spiritual path is to follow the footprints of predecessors, great ācāryas who has realized. Then you become perfect.
Not imitate, but to follow. Imitation is different thing. So this is not imitation, but this is following the footprints. So one who wants to become devotee, he has to follow certain rules and regulation which are enacted by authorized persons in this line. We cannot deny it. Therefore there is necessity. Yes?
