Asat means which will not stay, nonpermanent, for the time. Just like we have accepted this body. This is asad-grāha. This body will not stay. Everyone knows, but still, I am too much attached to this body. This is called asad-grāha. And so long we are attached to this nonpermanent body, there should be anxiety. Prahlāda Mahārāja says, asad-grahāt, sadā samudvigna-dhiyām asad-grahāt (SB 7.5.5). Because we have accepted this temporary body, therefore we are full of anxiety. Full of anxiety.
He was asked by his father, "My dear son, what nice thing you have learned? Kindly say." Father wants to know how his son is being educated. So Prahlāda Mahārāja replied that "My dear asura father," he said. Asura-varya. He did not say "father." He said, "My dear asura, the best of the asuras," asura-varya. Asura-varya, means best . . . that is the foolishness. The best—he heard the best, but he is addressing him as "asura, best asura," still he is pleased, because "I am best. I am best, best asura." So Prahlāda Mahārāja, a devotee, is very humorous, so he did not address his father as "father." He said, tat sādhu manye asura-varya: "O best among the asuras." (laughter)
So he said, tat sādhu manye: "I think it is very nice." Tat sādhu manye 'sura-varya . . . very nice for whom? Dehinām: "those who have accepted this material body." That means all material living being. Tat sādhu manye 'sura-varya dehināṁ sadā samudvigna-dhiyām: "who are always full of anxieties." That's a fact, full of anxiety. This is the test that we are in external material body. Therefore we are anxious. Tat sādhu manye 'sura-varya dehinām asad-grahāt sadā samudvigna-dhiyām. So for them this is the best formula. What is that? Hitvātma-pātaṁ gṛham andha-kūpam. He should give up this so-called family life, which is just like a dark well. Hitvātma-pātam. The dark well . . . in the paddy field or in agricultural field they are . . . formerly they used to dig wells, and sometimes they are covered with grass, and one man cannot know that there is . . . (break) . . . and he should go to forest. Vanaṁ gataḥ. Then what will be the benefit? Now, harim āśrayeta: "Just take shelter of Kṛṣṇa." Instead of taking shelter of these lusty desires, you take shelter of Kṛṣṇa. Then your life is successful.
