Devotee (5): We are becoming happy by distributing your books.
Prabhupāda: Thank you. It is Kṛṣṇa's book. You have got that cake? Give them.
Devotee (5): I was going to say, Śrīla Prabhupāda, I was talking, and I gave a family a big..., a husband and a wife, a big Kṛṣṇa book. The husband took the Kṛṣṇa book. The wife was indifferent. A year later the wife read the Kṛṣṇa book and left her husband and joined the temple, just from reading the one book. And I was very enlivened by this. When you can see the results like that, you become enlivened.
Tripurāri: Just by distributing your books we can become self-realized.
Prabhupāda: You are already self-realized. Otherwise how you can push on the books? You love Kṛṣṇa. Therefore you are taking so much labor for pushing on. And that is self-realization. If anyone tries to establish that Kṛṣṇa is the Supreme Lord, that is self-realization.
Tripurāri: Sometimes the devotees ask if they can take birth again distributing books for you.
Prabhupāda: Very good. That is real devotion. A devotee does not want to go to Vaikuṇṭha or any liberation. They are satisfied with the service. That is pure devotion. And distributing books for the benefit of going to Kṛṣṇa, that is selfishness. But "I want to simply distribute the books without any remuneration, without any my personal..." that is pure devotee.
Just like Prahlāda Mahārāja says that "I do not wish to go to Vaikuṇṭha unless I take all of these rascals with me." That is pure devotee. Pure devotion does not mean to... He is always under the protection of Kṛṣṇa. What is the use of going Vaikuṇṭha or...? Wherever he stays, that is Vaikuṇṭha. That is pure devotional service. Mama janmani janmanīśvare bhavatād bhaktir ahaitukī: [Cc. Antya 20.29, Śikṣāṣṭaka 4] "Life after life I may go on with this business. I don't want anything." That is pure devotion. (About cake:) So distribute.
