Prahlāda Mahārāja is appreciating that "I am worthless. I have no qualification." That should be the position of the bhaktas always. Never we should think that "I have become a big bhakta." No. Caitanya-caritāmṛta author says humbly, puriṣera kīṭa haite muñi se laghiṣṭha: (CC Adi 5.205) "I am lower than the worm in the stool." Does it mean that he is actually? No. But he's feeling like that. An advanced devotee, they're always so humble and meek, they always think of himself as worthless. And still, the Lord is so kind and favorable. That is His causeless mercy, that "I am not qualified, I am not worthy of this facility." This is the humbleness. Kvāhaṁ rajaḥ-prabhava īśa tamo 'dhike 'smin. "Not only I am influenced by rajo-guṇa, but mostly, seventy-five percent, I am infested with tamo-guṇa." Adhika. Akhika means "in larger quantity." And there is no question of sattva-guṇa. Adhika 'smin jātaḥ sure... "Otherwise why I am born in this family?" That is the test. Now they are... By force they are trying to be equal. Of course, in this age everyone is śūdra. That is an... Otherwise lowborn means this differentiation of different low qualities. By nature it will give. I have several times explained that as you infect a certain type of contaminous disease, you get that, you suffer from that. So the brāhmaṇa, kṣatriya, vaiśya, śūdra, then antaja, (?) caṇḍāla, mean, so many, kirāta, hūṇa, pulinda, pulkaśā, abhīra, śumbha—so many, low-grade, low-grade, low-grade, low-grade, low-grade. Then why this low-grade birth? That is due to this kāraṇaṁ guṇa-saṅgo 'sya (BG 13.22). In the Bhagavad-gītā it says. It is due to our association with low-grade qualities.
Therefore the human life should be very cautious that we may not be contaminated by low-grade qualities. There are so many rules and regulations, but it is very very difficult to follow. Therefore Caitanya Mahāprabhu has recommended, just to remain purified, "Chant Hare Kṛṣṇa." Harer nāma harer nāma harer nāma eva kevalam, kalau nāsty eva nāsty eva (CC Adi 17.21). You cannot... Otherwise you cannot purify. So kīrtanīyaḥ sadā hariḥ (CC Adi 17.31). We should always chant Hare Kṛṣṇa mantra. Then we'll gradually be spiritualized, cinmaya, spiritualized. Then our life will be successful.
