So spiritual life means anxiety-less. This is the difference between material life and spiritual life. Brahma-bhūtaḥ prasannātmā (BG 18.54). In the Bhagavad-gītā it is described what is spiritual life. As soon as you are identified with the Absolute Truth, Brahman, then symptoms will be prasannātmā, jubilation: "Oh, I do not belong to this material world; I belong to the spiritual world. I am part and parcel of Kṛṣṇa.
Why should I suffer so many things?" That is jubilation. Brahma-bhūtaḥ prasannātmā. The prasannātmā means na śocati na kāṅkṣati (BG 12.17). He has no lamentation, no hankering. Here people are always full anxieties because they have got hankering: "I want this. I want that." And there is lamentation. What they possess, if it is lost, they cry, "Oh, my things are lost." And what they do not possess, they hanker.
So their anxiety is there, either he possesses or not possesses. This is material anxiety. If you have no money, then you will hanker after money, "How to get money? How to get money? How to get money?" And when you get money, then how to utilize it, how to . . . where to keep it, in the bank, or in the house, or who will take away—somebody will take away. So where is anxiety-less? You possess or not possess, the real disease is anxiety. So when one becomes brahma-bhūta, self-realized, identified with the Absolute Truth, then he has no more anxiety. This is the best education, when you become anxiety-less. That is perfection of education.
So when Prahlāda Mahārāja was inquired by his father that "What nice thing you have studied, my dear boy, in your school?" so he replied, "My dear father, the best education I have received: how to become anxiety-less." That's all. Tat sādhu manye 'sura-varya dehinām (SB 7.5.5). "Not only for me, but for everyone. But you will not understand, my dear father, because you are demon number one." (laughter) He is addressing his father, asura-varya. Asura-varya. Asura means demon, and varya, varya means the first class. (laughter) (chuckles)
He is not addressing his father as "My dear father"; "My dear best of the atheists." Therefore his father was very angry, "This child, he talks with me on equal level and does not fear me. Kill him!" Asura. He is prepared to kill his son even, if he does not agree with him. You see? We are also prepared. If one is not devotee, if he is son, we can kill him. The same. But our is for Kṛṣṇa, and the asuras is for himself. That is the difference. He wants to do everything for his personal satisfaction, and we want to do everything for Kṛṣṇa's satisfaction. That is the difference. The same propensities are there, but when it is applied for Kṛṣṇa, then it is purified, and when it is applied for personal self, it is impure. This is the difference.
So Prahlāda Mahārāja said, "The best education is that which makes one anxiety-free." That is best education. Now where is that education? Is there any education throughout the whole world, in so many universities, especially in your country there are nice, very, very . . . rather, they have created so much anxieties that the boys, they are frustrated. They are giving up everything, becoming hippies. Where is anxiety-less? They increase anxiety. Increase anxiety. Tat sādhu manye 'sura-varya dehināṁ sadā samudvigna . . . "My dear father, the best of the asuras, I think that anyone who has accepted this material body is full of anxieties." Asad-grahāt. Asad-grahāt means . . . asat means temporary. Because he has accepted a body which is temporary, he is full of anxieties. That is the real problem. We, if we want to be anxiety-less, no anxiety, then we have to refuse to accept this material body. Otherwise there is no possibility. All anxieties are due to this material body.
