Generally, the gross fools and the ignorant fruitive workers do not surrender to the Supreme Lord. Such people never enquire into the Absolute Truth. They never ask such questions as "Who is God?" "What is the world?" "Who am I?" "Why am I working like an ass my whole life?" or "What is the result of my endeavors?" The ass slaves his whole life carrying the washerman's burden, just for a handful of grass. Similarly, the karmīs (fruitive workers) toil tirelessly simply to secure a supply of food and other necessities. The ass is a symbol of foolishness, for he works hard only to fill his belly and copulate with a she-ass. So also do the asinine karmīs toil tirelessly out of affection and attachment, struggling to maintain their homes and, beyond that, the land of their birth, which they consider worshipable. In the home the karmī's sole source of enjoyment is his wife, who cooks for him and provides pleasure for his misery-ridden senses. The shortsighted karmīs do not want to know of any broader issues concerning themselves or their world; they are simply tethered to their home and bodily cares. And those leaders who foster the people's sensual lives are bigger fools and rascals than the ordinary karmīs. Therefore they never come in contact with the Bhagavad-gītā or Lord Kṛṣṇa. The word surrender means nothing to them.
People who do not surrender to the Supreme Lord are called narādhama, "the lowest of men." Such men fritter away their human lives, behaving like animals. In other words, when a person does not use this rare human birth to achieve its actual purpose but wastes it in degraded activities, he is called a narādhama. When a beggar suddenly finds a treasure yet continues to live like a beggar, he is surely a miser and a narādhama. Similarly, when someone receives the priceless gift of a human birth yet squanders it by living like an animal—simply eating, sleeping, mating, and defending—then such a person is a narādhama. These fools do not realize that after many millions of births in lower species, the soul finally receives the rare human birth. And it is in this birth that the soul must sincerely endeavor to elevate himself to the transcendental platform, attain the Absolute Truth, and return to his original home in the spiritual world. If in this human life the soul makes no attempt to alleviate his situation, even after learning how horribly he has suffered in millions of previous lifetimes, then such a person is certainly a miserable miser and narādhama. But if one tries to utilize his rare human birth for self-realization by becoming elevated to the brahminical class, then his life is successful. Brāhmaṇa does not mean brāhmaṇa by birth. A brāhmaṇa is one who surrenders to Lord Kṛṣṇa, the Lord of the brāhmaṇas. A narādhama cannot do so. Therefore another meaning of narādhama is "one who rejects devotional service."
Another class of men who do not surrender to Lord Kṛṣṇa are the demons, those who are staunchly inimical to Him. Famous and powerful demon kings like Rāvaṇa, Hiraṇyakaśipu, Jarāsandha, and Kaṁsa acquired many mystic powers through learning and severe austerities. But because they always challenged the various incarnations of the Supreme Lord, such as Lord Rāma, Lord Nṛsiṁhadeva, Lord Viṣṇu, and Lord Kṛṣṇa, they are known as demons. Often the demons do not lack education or intelligence, but because of their fiendish mentality toward the Supreme Lord, their learning and brain capacity come to naught. Their abilities, being fully in the grip of material nature, are ultimately taken from them. The reason for the demons' failure has been stated earlier: If one does not surrender to Lord Kṛṣṇa, it is impossible to surmount material nature.
