Prabhupada: Brahmana means whose knowledge is so perfect that he knows what is God. That is brahmana. And sudra means one who laments. Socati ti sudra.[?] Socati.

Srutakirti: Na socati na kanksati.

Prabhupada: Socati means in everything he laments. "Hai, hai, I have lost so much things. I have not these things, I have not that thing." So at the present moment, all the people, they are so dissatisfied that they are all sudras. Sudra is always in want. So who is not, at the present moment, not in want? Everybody's in want. Therefore everybody is a sudra now. Kalau sudra-sambhavah. And that is his qualification, always feeling in want, socati. And his work is to serve others, master. A brahmana will not work under anybody. A ksatriya will not work under anybody. Nowadays the industrial development has taken place because people are sudras. They want some service. So-called technologist and laborers and..., everything. Everyone is searching after good job. He cannot live independently. Just like a dog. A dog cannot live independently. He must have a master. Then he is happy. Is it not? Otherwise it is street dog.

Tamāla Kṛṣṇa: Cow is going to die naturally, anyway.
Prabhupāda: Yes. Then, if you want flesh, take that dead body and eat.
Tamāla Kṛṣṇa: Why don't they see this, that just by killing a cow you don't get more cows. They're going to die anyway.
Prabhupāda: Yes. Everyone is going to die, but they are so voracious, they do not wait up to the death, and they have theorized that "Dead animal is dangerous to health. Now kill while it is in life."
Harikeśa: Yes, they think like that.
Prabhupāda: Yes, but... They have got so many nonsense philosophy. But if that philosophy is supported, when you kill the animal, he becomes dead. (laughter)
Sudāmā: Yes, they call it "fresh meat."
Prabhupāda: Just see. "Fresh dead." Just see. The rascals are so fools that unless you make him dead, you cannot eat. So why do you theorize that a dead animal is not good?
Harikeśa: Well, 'cause he had to die from some cause, and that cause is...

Generally people think that simply by executing the occupational duties of a brahmana, ksatriya, vaisya or sudra or the duty of a brahmacari, grhastha, vanaprastha or sannyasi one becomes fearless or securely attains liberation, but factually unless all these occupational duties are accompanied by bhakti-yoga, one cannot become fearless. In Bhagavad-gita there are descriptions of karma-yoga, jnana-yoga, bhakti-yoga, dhyana-yoga, etc., but unless one comes to the point of bhakti-yoga, these other yogas cannot help one attain the highest perfection of life. In other words, bhakti-yoga is the only means for liberation. We find this conclusion also in Caitanya-caritamrta in a discussion between Lord Caitanya and Ramananda Raya regarding a human being's liberation from this material world. In that discussion Ramananda Raya referred to the execution of varnasrama-dharma, and Lord Caitanya indicated that the varnasrama-dharma was simply external (eho bahya). Lord Caitanya wanted to impress upon Ramananda Raya that simply by executing the duties of varnasrama-dharma one is not guaranteed liberation. Finally Ramananda Raya referred to the process of bhakti-yoga: sthane sthitah sruti-gatam tanu-van-manobhih (SB 10.14.3). Regardless of one's condition of life, if he practices bhakti-yoga, which begins with hearing (sruti-gatam) the transcendental messages of the Lord through the mouths of devotees, he gradually conquers the unconquerable God.
God is known to be unconquerable, but one who submissively hears the words of a self-realized soul conquers the unconquerable. The conclusion is that if one is serious about liberation, he not only should execute the occupational duties of varnasrama-dharma but should also engage in bhakti-yoga by beginning hearing from a realized soul. This process will help the devotee conquer the unconquerable Supreme Personality of Godhead and become His associate after giving up the material body.
