Śrīmad-Bhāgavatam 7.9.39

Māyāpur, March 17, 1976
So Prahlāda Mahārāja in another place has said also the same thing. When his father asked him, "What is the best thing you have learned, my dear boy, from your school?" so he immediately addressed his father as asura-varya. Why? Now, because this thing, free of anxiety, is not understandable by the asuras. They want anxiety. They'll create such situation. They'll put themselves in anxiety and try to come out of it. That is their heroic activities. This is the difference between the asura and the sura, devatā. The devatās, or the devotees... There are two different types of men. One is asura, and the other is devotee, just like Prahlāda Mahārāja and his father Hiranyakasipu. These two types of men are there in this world. And the difference we can see, that Prahlāda Mahārāja is simply satisfied with Kṛṣṇa. Prahlāda Mahārāja says,
naivodvije para duratyaya-vaitaraṇyās tvad-vīrya-gāyana-mahāmṛta-magna-cittaḥ
[SB 7.9.43].
Prahlāda Mahārāja, when he saw Nṛsiṁhadeva, very fierceful... Even mother Lakṣmī, the goddess of fortune, who is constant companion of the Lord, she also became afraid, and what to speak of other demigods like Brahma, Lord Śiva and Indra and so many others? All of them became afraid. Nobody could approach Him. He was so angry. But Prahlāda Mahārāja said that "I am not afraid." He said, "I am not afraid."
Naivodvije para duratyaya-vaitaraṇyās tvad-vīrya-gāyana-mahāmṛta-magna-cittaḥ.
A devotee who is always absorbed in the thought of Kṛṣṇa and His activities... We are therefore presenting Kṛṣṇa and His activities. This is our Kṛṣṇa consciousness movement. All these books which we are distributing and publishing, what is this? This is Kṛṣṇa and His activities, that's all. Tvad-vīrya-gāyana-mahāmṛta-magna. So if you simply read our books very carefully, then immediately this disease of heart palpitation, anxiety, will cease because on account of the dirty things, product of this tamo-guṇa and rajo-guṇa... That is disturbing us. We are covered by the tamo-guṇa and rajo-guṇa, rajas-tamaḥ. So rajas-tamaḥ means greediness and lusty desires. This is rajas-tamaḥ. So we have to... If we actually want to become free from anxieties, then we have to learn how to kill this, or how to avoid this anxiety due to rajas-tamo bhāvaḥ [SB 1.2.19].
