Arcanaṁ vandanaṁ dāsyam. To be always in service of the Lord, dāsyaṁ; sakhyam, to make friendship with Him, to consider Kṛṣṇa as your friend. He says . . . even if I do not say that He's my friend, He says: "I am friend of everyone." Suhṛdaṁ sarva-bhūtānām (BG 5.29). He's friend of everyone. We don't want His friendship, but He wants our friendship. He wants us to go back to home, Godhead; we don't want. So He is more anxious to take us, exactly like the father is more affectionate than the son. That's a fact.
So He's the supreme father. So He wants that we may be happy, and therefore He comes to show us. He sends His representative, son. He leaves behind Him books so that we may go back to home, back to Godhead. So sakhyam. He's always sitting with me, within my heart. I am in the heart, and Paramātmā is also within the heart as friend, to give me advice that "Why you are bothering in this material world? Please come back to home, back to Me." This is going on. Sakhyam ātma-nivedanam. Ātma-nivedanam means fully surrendered. So there are examples of devotees who, sarvātma-nivedanam. Just like Bali Mahārāja: he gave everything to Kṛṣṇa, even his body—everything, whatever: his kingdom, money, everything.
So Prahlāda Mahārāja says, iti puṁsārpitā viṣṇau bhaktiś cen nava-lakṣaṇā. All these items means hearing—hearing about Viṣṇu, chanting about Kṛṣṇa, giving everything to Viṣṇu, offering prayers to Viṣṇu, offering arcana, temple worship, Viṣṇu. In this way Prahlāda Mahārāja summarizes that "Anyone who is doing like this, everything about Viṣṇu," iti puṁsārpitā viṣṇau bhaktiś cen nava-lakṣaṇā, "this nine kinds of different devotional services," kriyeta bhagavatay addhā, "directly to the Supreme Personality of Godhead," tan manye 'dhītam uttamam, "I think he is the best learned man in the world. He is the most learned." Tan manye 'dhītam: "He has studied everything very nicely."
Actually, that is the fact. Jñāna, knowledge . . . knowledge means to know Kṛṣṇa, God, and the Vedic injunction is, yasmin vijñāte sarvam evaṁ vijñātaṁ bhavanti (Muṇḍaka Upaniṣad 1.3). If you understand the Supreme Lord, then you understand everything. You haven't got to study differently different subject matters. Just like we sometimes talk of science, of astronomy, economics, politics. We talk sometime. But we are not going to, or we didn't study all the subject matter separately. But in course of our studying Kṛṣṇa consciousness, we know something of everything. So Prahlāda Mahārāja says, tan manye adhītam uttamam (SB 7.5.24): "One who is engaged in these nine kinds of devotional services directly."
