Mālatī: I don't understand how materialistic people, if they have material minds, they can remember their past lives.
Prabhupāda: Material mind has to be treated by spiritual medicine, then the material mind will be spiritual. Just the same example, that a man has got some bowel disturbance by drinking excessive milk, and the physician gives him another milk preparation, curd, and he is cured. Similarly, the Kṛṣṇa consciousness movement is just to treat the mind by Kṛṣṇa engagement. Then he becomes freed from material contamination. And actually it is happening. Those who are taking to this treatment, they are experiencing how it is happening. The door is closed? Why? Open. (kīrtana) (end)
