One book is named Kṛṣṇa-karṇāmṛta. That book was written by one of the devotees, very great devotee, Bilvamaṅgala. His life is very interesting. He was too much prostitute-hunter. In one incidence his kept prostitute gave him instruction, "Oh, you have got so much attraction for this skinny body. If you would have such attraction for Kṛṣṇa, I do not know what you have done." Oh, at once he became, "Yes." This is called reference to the context. Because he, that gentleman, in his previous life he cultivated Kṛṣṇa consciousness to the highest degree, but somehow or other, it was stopped. And as soon as the same thing was pointed out, he began again from that point. That is the process of Kṛṣṇa consciousness. Even if we do not perform the whole process of Kṛṣṇa consciousness, whatever we do, that remains in asset. That is never lost. So this Bilvamaṅgala Ṭhākura, from that prostitute's house he became a saintly man. So he wrote a very nice book, Kṛṣṇa-karṇāmṛta. Kṛṣṇa-karṇāmṛta means "pleasing to the ear." Anything about Kṛṣṇa is pleasing to the ear. So he wrote a voluminous book, Bilvamaṅgala Ṭhākura. That book was collected by Lord Caitanya. And along with that book, this Brahma-saṁhitā was collected.
