So similarly, if our attachment becomes very nice, very mature, for Kṛṣṇa, then this viraktata, or detachment for material things, will automatically happen. But that is required, viraktata. And maunam. Mauna. Mauna means don't talk; grave. This is also very good qualification because generally, when we talk, we simply talk nonsense. That's all. We shall sit together, and some friends or family, some useless talks, we shall go on for hours together. But if you are called to talk about Kṛṣṇa or Bhagavad-gītā or Bhāgavata, this philosophy, nobody will come. So better not to talk. It is better not to talk than to talk nonsense, foolish.
So generally, we are accustomed to talks, enjoy foolish talks, which has no meaning, neither any benefit for this material world, neither any benefit for spiritual world. If you are, of course, gaining something material benefit . . . just like businessmen talk. They talk seriously if there is any profit. Otherwise the secretary says: "Oh, the Mr. Such-and-such has no time to see you." That is also some good, because time is so valuable. So why should we talk nonsense?
So that is also very good qualification if we don't talk nonsense. Either you talk about Kṛṣṇa or don't talk. That is called mauna. If there is no subject matter for talking on the subject of Kṛṣṇa, then it is better not to talk. But we have got very nice engagement. We can talk Hare Kṛṣṇa. If you have no other engagement, then we have got these beads, "Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa . . ." You can day and night, twenty-four hours, go on. This is called mauna.
And vijṣāna. Vijṣāna means perfect knowledge. What is that perfect knowledge? Perfect knowledge means to know Kṛṣṇa. Yasmin vijṣāte sarvam evaṁ vijṣātaṁ bhavati (Muṇḍaka Upaniṣad 1.3). The Vedic injunction is, "If you can understand the Supreme, then you understand the whole thing, because Supreme is the whole, absolute." Just like if you can understand one, two, three, four, five, six . . . eight, nine, zero, then you can understand the whole mathematics, because what is mathematics? One, two, three, four, three, four, one, two, just like that. That's all. The same nine figures, that's all.
Similarly, the Vedas says, yasmin vijṣāte sarvam evaṁ vijṣātaṁ bhavati (Muṇḍaka Upaniṣad 1.3). If you simply try to understand the Supreme Absolute Truth, that is the purpose of Vedas. And it is confirmed in the Bhagavad-gītā also, vedaiś ca sarvair aham eva vedyam (BG 15.15). What is the use of studying Vedas? What is the use of studying this Bhāgavata or . . .? To understand Kṛṣṇa. That's all.
