Guest (2): Does any physical change take place in your body when you become Kṛṣṇa conscious?
Prabhupāda: Yes. There are so many physical changes. We have seen it practically. Yes. Some of our students, so long he was here, he was so nice. He was so glowing. And as soon as he has left, he has become just like damn rascal. Yes. We are experiencing practically. There are so many instances. Because my face is the index of mind, so similarly, what is going on within you, that will be reflected. That will be reflected. Caitanya Mahāprabhu was asked that "How can I understand...?" One of His disciples inquired from Caitanya Mahāprabhu, "How can I understand that a man is in Kṛṣṇa consciousness?" He immediately replied, "If you see a man and at once you remember Kṛṣṇa, you must know that he is in Kṛṣṇa consciousness." It is such a nice thing. By seeing the face, by seeing the appearance of a person, if you remember Kṛṣṇa, you should know that "This man is in Kṛṣṇa consciousness." So there is change of physical feature also.
