Prabhupāda: Vṛndāvana cannot be polluted. Just like within the heart of a hog there is Kṛṣṇa. It does not mean Kṛṣṇa's staying in polluted place. The sunshine may be in the filthy place, but sun is not polluted. But the filthy place is purified.
Guest (3): The human society is degrading so fast. You can notice it the last twenty years. Is it... Is it the age of Kali or is it the...?
Prabhupāda: Yes. Due to age of Kali. Yes. Due to the age of Kali, it is degrading. So only we can save by Kṛṣṇa consciousness movement. If not all, some of them can be saved.
Guest (3): It can be changed, the age of Kali, by presence of the devotees of Kṛṣṇa?
Prabhupāda: Yes. Why not? It will change in the Satya-yuga. Just like our body is changed, season is changed, similarly, this will also change.
