Prabhupāda: You can avoid even Deity worship, but you cannot avoid chanting.
Devotee: Their idea is to abolish Deity worship. They consider it antiquated.
Prabhupāda: If you want... If you want... Why you should try to avoid this? That means you are disregarding the śruti-smṛti. But that is not the policy, that you should avoid it. But if you..., it is not possible... Just like it is not possible to introduce the Deity worship everywhere, anywhere. It doesn't matter. You chant Hare Kṛṣṇa. It is not avoiding. It is the circumstance that does not make very favorable. Just like I did not introduce the Deity worship in the beginning. That was not possible. But when there is favorable condition we introduced. That is not avoidance. That is conditional. But especially chanting, that is possible in any condition of life. That is possible.
Puṣṭa Kṛṣṇa: So there's no question then, as he says, of bringing new smṛtis which would come into being if someone would give them sanction and authority. The position as you...
Prabhupāda: But there cannot be new smṛtis. We are giving the sanction to Hare Kṛṣṇa mahā-mantra because it is already there in the śruti. But for this time it is suitable. I am taking a certain type of medicine in the evening, it is already recommended by the physician. I am not doing it whimsically. So whimsically you cannot change. It must have reference to the śruti-smṛti-purāṇadi (BRS 1.2.101).
Puṣṭa Kṛṣṇa: Can anyone change...
Puṣṭa Kṛṣṇa: ...the rules of conduct as regarded in the smṛtis?
Prabhupāda: Nobody can change. Nobody can change. But rules and regulation for different times, different circumstances are there in the śruti-smṛti. We have to take it. You cannot change.
Puṣṭa Kṛṣṇa: And who will sanction that application?
Prabhupāda: Yes. Just like Caitanya Mahāprabhu. He said. He's authority. He's ācārya.
Puṣṭa Kṛṣṇa: The ācārya must sanction for the particular time and place.
Prabhupāda: Yes. We are following the footprints of Caitanya Mahāprabhu. It is not whimsical. You have to follow the authority in all circumstances. You cannot avoid. That is illegal. It will have no power. Just like all of a sudden you make a low class man a harijana. It will not stay. But you can make harijana any class of man provided you adopt the proper means.
