Everything is being supplied by Kṛṣṇa. Therefore He's Supreme Being. How He can be supreme? Just like in a family the father is considered to be supreme. Why? Because he takes care of the whole family, he is supreme. Similarly, the Supreme Person, Kṛṣṇa, He takes care of the whole creation, material and spiritual, innumerable universes, and therefore He's sup . . .
So when we act according to the direction of the Supreme . . . because we are subordinate. This is our position. A subordinate position is that he must act according to the direction of the master or the supreme. That is natural. Everyone is acting like that. So that is called buddhi-yoga. When you act according to the direction of the Supreme, Kṛṣṇa, or His representative, that is called buddhi-yoga. That is real . . . Buddhi means intelligence, and yoga means linking, connecting. In the Tenth Chapter you'll find:
- teṣāṁ satata-yuktānāṁ
- bhajatāṁ prīti-pūrvakam
- buddhi-yogaṁ dadāmi taṁ
- yena mām upayānti te
- (BG 10.10)
There is the buddhi-yoga, one word, and here is also the buddhi-yoga.
So what is that buddhi-yoga? Kṛṣṇa says, teṣāṁ satata-yuktānām: "Persons who are twenty-four hours engaged," satata. Satata means always. Engaged. What kind of engagement? Bhajatāṁ prīti-pūrvakam. This engagement means always trying to render some service to the Lord. How? Prīti-pūrvakam: "with love and faith." Not that, "Oh, I have to do it? All right, let me do." No. "Oh, I have to do it? Let me do it nicely." Unless there is love, you cannot do it nicely, any matter. In the material world also, unless you have got some attachment for something, you cannot act it very nicely. Just like a musician. Because one has got a good attachment for music, he tries to perform it very perfectly. So love is the basis.
Similarly, when you serve Kṛṣṇa, if you have no love for Kṛṣṇa, you cannot serve Him very nicely. And Kṛṣṇa also does not accept your service if it is not done in great love and affection. That is the basic principle. Kṛṣṇa does not require your service. He is self-sufficient. He has got many servants, anywhere and everywhere. So Kṛṣṇa does not require our service. It is our interest. If we render service to Kṛṣṇa, then we become happy. That is the profit. Teṣāṁ satata-yuktānāṁ bhajatāṁ prīti-pūrvakam (BG 10.10).
