So Vyāsadeva summarized all the Vedic literature in the Vedānta-sūtra.
Veda means knowledge; anta means end. There is . . . everything, there is some summit or the ultimate goal. So about education, knowledge, the ultimate goal is Vedānta. Veda means knowledge; anta means ultimate. If you know Vedānta, then you have known everything. Yasmin vijñāte sarvam idaṁ vijñātaṁ bhavati (Muṇḍaka Upaniṣad 1.3). So still, after compiling Vedānta-sūtra philosophy, Vyāsadeva was not satisfied. He was feeling some vacancy. He was sorry.
So his spiritual master, Nārada, appeared before his disciple Vyāsadeva. So Nārada could understand that Vyāsadeva was not happy even after compiling so many big, big volumes of literature, Vedic literature. So he questioned, "Pārāśara . . ." Vyāsadeva's father was Parāśara Muni. So he addressed him, "Pārāśara." So "Why you are unhappy? You have studied everything. You have undergone all kinds of penances. You have performed all Vedic rituals. You have written so many books.
Why you are unhappy?" He answered, "My dear lord, what you say, it is all right, that I am not happy. But you can find out the cause. Because you know everyone's heart, you can find out the cause." So Nārada Muni replied that—these things will be discussed in the Śrīmad-Bhāgavatam—that, "You have considered so many things, but if . . . you have not written anything absolutely for the Supreme Personality of Godhead. Without discussing about the Supreme Personality of Godhead, you cannot be happy."
That is the fact. At the present moment also, there is advancement of education—many universities, many technological institutes, economic development. In your America there is everything sufficient, but still, people are unhappy. They are becoming hippies. Why? Because there is no knowledge about God. This is the only cause. This is the only cause.
Every one of us is part and parcel of God, so our real hankering is God. Just like child, baby, is the part and parcel of the mother, and when the child is unhappy, nothing can satisfy the child except when he is put on the lap of his mother. He is crying, everybody is trying to pacify him, but the child is going on crying, crying. But as soon as you put him on the lap of his mother and the mother takes on his (her) breast, the child is immediately happy. Similarly, we are all children of God. We are making so many plans to become happy independently, without God. That is not possible. That is not possible. Therefore there is great necessity of understanding God at the present moment. Therefore this Kṛṣṇa consciousness movement is started.
