There are three classes of men. One class of men, karmīs, they are trying to enjoy the material resources. Icchatām, always desire. "I want this, I want this, I want this." And another class, they are con... or rather, what is called? Frustrated. After trying utmost, "I want this, I want this, I want this," when at the end do not get anything, he is frustrated. That is called nirvidyā. "I don't want." Or actually one is satiated or disgusted. "No more material world. I don't want it." They are called nirvidyamānānām. So the one class is trying to possess and another class is trying to renounce. "I don't want." And another class is akuto-bhayam. Akuto-bhayam. Who is akuto-bhayam? Akuto-bhayam means one who does not fear. And who does not fear? Because fearfulness is one of the items of our conditional life. Āhāra-nidrā-bhaya-maithuna. Eating, sleeping, fearing, and mating. So who is without any fear? That means he's also liberated. He's not in the material platform, transcendental. Who is out of the limits of fearfulness.
So akuto-bhayam means the devotees. The devotees, just like Prahlāda Mahārāja, his father teased him in so many ways but he was not at all fearful. He was simply thinking of Nṛsiṁha-deva and he was fearless. So only the devotee who has fully surrendered to Kṛṣṇa, he can be fearless. Nārāyaṇa-parāḥ sarve na kutaścana bibhyati (SB 6.17.28). Nārāyaṇa-parāḥ means devotees who have dedicated their life to the service of Nārāyaṇa, Kṛṣṇa. Na kutaścana bibhyati. He does not fear in any condition of life. So here, icchatām akutaḥ. Icchatām means those who are desiring. Nirvidyamānānām means those who are not desiring, renouncing. And the other class, akuto-bhayam, fearless. And yoginām. Another class-mystic yogis. So generally, these four classes men are there. So Śukadeva Gosvāmī says that for all of them, either he is karmī or he is jñānī or he is yogi or he is bhakta. Karmī means fruitive worker, and jñānīs means empiric philosophers, and yogis, mystic, I mean to say, yogis, and bhaktas, and the devotees. Generally, these four classes of men.
