Harikeśa: What if a person doesn't desire material enjoyment, but still, there is so much dirt?
Prabhupāda: Hm? Who is that person who has no material desires?
Harikeśa: A person really wants to be Kṛṣṇa conscious, but somehow or another, so much dirts gets in the way.
Prabhupāda: Yes. Dirt means it is not yet zero. I said that all material desires should be made zero. Anyābhilāṣitā-śūnyam (Brs. 1.1.11).
Harikeśa: As soon as the desires completely change, then everything else is purified.
Prabhupāda: Yes. As Arjuna said, kariṣye vacana tava, naṣṭo mohaḥ: "Now my illusion is over. I agree to act as you say." This is Kṛṣṇa conscious. Naṣṭo moha smṛtir labdh tvat prasādān madhusūdana. (break) The moha is there. Moha means these desires are illusion, like dreaming. In dream we see so many things. They are all false. In dreaming I am seeing that somebody is coming to kill me but there is nobody, but still, I am dreaming. This is called moha. So when one is free from moha, then he's Kṛṣṇa conscious. The whole material world is going on under such illusion. Therefore it is called māyā.
